The answer would be survival of the fittest.
This metaphor, "<em>survival of the fittest</em>," was used by Herbert Spencer to explain <em>natural selection. </em>It is sometimes also referred to as the survival for existence. This phrase came from the Dawinian theory of evolution where he explains that all species are capable of producing many offsprings. However, the survival of those offsprings depends on their ability to adapt to the risks and opportunities of the external environment.
<em>
</em>This relates to your scenario in the sense that fish lay a lot of eggs in the beginning but not all of them would live to achieve maturity. This is because even as eggs, they have many predators and are exposed to other elements. The threat pushes on even if they are able to hatch and grow up.

The correct answer is option (A) trichomes.
Trichomes are the fine extensions from the epidermal surfaces covering the plant body. They are the result of epidermal cell division. They can be unicellular, multicellular and even glandular. They are characteristically present on the epidermal surfaces of leaves and roots. They reflect the solar radiation and help in mainitaining the internal temperature and reducing water loss. In roots, they absorb water and minerals and in leaves, they reduce water loss, lower the plant temperature. Plants may use trichomes to detect herbivore attacks as a defense mechanism.

The nucleus is the largest and the most important cell organelle in a eukaryotic cell. A nucleus is a membrane-bound organelle that houses the genetic material of eukaryotes in DNA. The nucleus consists of protein fibres or the DNA inside chromatin fibres. Nucleoids contain the genetic material of prokaryotes in the cytoplasm. The nucleoids usually consist of a single chromosome.
Let us look at more difference between nucleus and nucleoid in the table given below.
