The right answer is B.
The answer B is the only proposition which specified at which stage the event must occur, in fact, the meiosis.
Meiosis is a characteristic division of reproductive cells that can generate gametes to form new species (desendence). So if a mutation occurs at this time (such as recombinations) it will inevitably be inherited.
Answer:
Oil workers activities involved in the exploration of crude oil and natural gas creates pollution which affects the ecosystem negatively. The various pollutions cause the death of plant and animal life both on land and in water bodies.
The oil workers should be more careful in their activities to prevent oil spillage as much as possible and if there is any at all then there should be adequate measures in the cleaning it up efficiently through biological and harmless chemicals.

Explanation:
Since scientific terms are harder to understand, some common prefixes (word added to beginning of another) , suffixes (word added at the end) and root words can be used to correctly guess the meaning of a biological term. Most of the terms have been derived from ancient Greek and Roman words.
- The prefix omni- means all. E.g, an omnivore is a type of animal that eats both plants and animals.
- Prim- is a prefix that means first or foremost. In some cases, it also means basic or fundamental. E.g the primal instincts of any animal are its basic and innate characteristics.
- Vor is a suffix that mean eat or devour. E.g, carnivore is an animal that eats meat.
- Oligo is a prefix that means few or little. E.g, oligosaccharide is a carbohydrate containing few sugar molecules.
- The prefix sub- means both under and below. E.g, subcutaneous means under the layer of the skin.
- The prefix sub- means both under and below. E.g, subcutaneous means under the layer of the skin.
- The prefix de- means remove, away from or down. E.g to degrade means to break down or break away.
- The prefix de- means remove, away from or down. E.g to degrade means to break down or break away.
- The prefix de- means remove, away from or down. E.g to degrade means to break down or break away.
- The prefix hydro means water. E.g, hydroelectric power is energy derived from water.
- Carn is a prefix that means flesh or meat. E.g, a carnivore is an animal that eats meat.
- The prefix zoo or zoa defines an animal or of animal origin. E.g, zoology i.e. the study of animals.
- The suffix, -cide means to kill or destroy. E.g, fungicide is a chemical that kills fungi.
- Auto is a prefix that means self. E.g, autophagy is the pahgocytosis or engulfing of the body cells by other cells of the body.
- Inter is a prefix that means between. E.g, intercellular means between the cells.
- The prefix heter or hetero means different or other. E.g, heterogeneous is a type of mixture that contains different types of elements.
- Troph is a suffix that means feed or nutrition or nourishment. E.g, autotroph is an organism that produces its food by itself.
- Calor means heat. E.g, calorimeter is an instrument that measures heat or change in heat.
- Ultra is a prefix that mean beyond. E.g, ultrasonics are sound waves that are beyond the audible hearing range.
- Intra is a prefix that means within. E.g, intracellular means within or in the cell.
- Photo is a prefix that means light. E.g, photosynthesis is a process that plants use to make food by capturing light.
- Para is a prefix that means beside, near, equal or alongside. E.g parathyroid is a gland near the thyroid gland.
