The correct answer is: If assertion is true but reason is false.
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.
