Assertion : Cephalisation is advantageous to an animal. Reason : Cephalisation improves the appearance of an animal.

  • A
    If both assertion and reason are true and reason is the correct explanation of assertion.
  • B
    If both assertion and reason are true but reason is not the correct explanation of assertion.
  • Correct answer
    C
    If assertion is true but reason is false.
  • D
    If both assertion and reason are false.

Solution

Cephalisation is the concentration of nervous tissue and sense organs in or towards the anterior end forming a distinct head. It provides greater prominence and domination of the head over the rest of the body. However, it does not improve the appearance of the animal.

Hence, the correct answer is option: 'C'.
