Answers (1)


The assertion is true, while the reason is partially true. Evolution is not a random process because it occurs through natural selection, which involves the non-random survival and reproduction of individuals with advantageous traits. However, genetic mutations can occur randomly, and their accumulation over time can lead to the evolution of new traits and species. Natural selection then acts upon these mutations, selecting for those that provide an advantage in a particular environment. Therefore, while genetic mutations are not directed towards a specific outcome, their selection is not random, making the assertion true, and the reason partially true.

Option 3 is the correct answer.
