Answer:

Correct Answer: D

Solution:

Originally it was an idea of Herbert Spencer, who used the phrase “the survival of the fittest” first time.

While Darwin named it as “natural selection”.

Due to various struggles for existence, only those individuals survive which are best fitted to new conditions of life and the least fitted are the first to perish.

These indviduals show high selective value and in the course of time show various adaptive modification.

The survival of the fittest is the result of natural selection, which enforces adapations.
