Answer:
B
Explanation:
B is the most likely consequence because of the following facts we are told:
- After apple trees were introduced, some apple maggots began feeding from and laying their eggs on apple trees
- Adult apple maggots will only mate on the type of tree on which they were born.
This provides a geographical isolation (because they are feeding and laying eggs on separate trees) and reproductive isolation (because they will only mate on the type of tree on which they are born).
These two factors increase the chances that apple maggots feeding on apple trees will only encounter those who have mated on the same tree, and continue to mate this way. Over time, the populations (i.e. apple tree vs hawthorn tree) will intermix less and less. This will mean the genetic pool will become distinct, and natural selection will be acting differently (different habitats and different genes), encouraging speciation.

The correct answer is (d) Prokaryotes.
The word pro means "before". They are usually unicellular organisms and sometimes multicellular. The first living organisms found on earth are supposed to be prokaryotes. They are divided into two species of bacteria Archae and bacteria. They lack membrane bound organelles and all the water soluble components are present without membrane in the cytoplasm. They have primitive features hence a fossil found indicates towards prokaryotes.
