Answer
A is False and R is True.
Explanation
"Survival of the fittest" is a concept associated with Darwin's theory of natural selection, not Lamarck's theory. Lamarck's theory is based on the idea that characteristics acquired during an organism's lifetime can be passed on to its offspring.
Lamarck used the example of the giraffe's neck to illustrate his principle of 'use and disuse,' suggesting that giraffes stretched their necks to reach higher leaves, and this trait was then passed on to their offspring.

Assertion. The analogous organ to the vermiform appendix in herbivorous mammals is quite helpful in digesting cellulose. But it is considered a vestigial organ in humans.

Reason. Natural selection operates through the preservation of favourable variations that enhance an organism's ability to survive and reproduce, leading to the gradual adaptation of populations to their environments over time.
