Question

Assertion (A): Bilaterally symmetrical animals are more efficient in seeking food, locating mate etc.
Reason (R): Cephalization.

• A. Both A and R are true. R is correct explanation for A
• B. Both A and R are true. But R is not correct explanation for A
• C. A is true. But R is false
• D. A is false. But R is true

Hint:

Cephalization plays a significant role in improving the efficiency of bilaterally symmetrical animals in food seeking, mating, and overall behavior, as it allows better coordination of sensory inputs and motor functions.

Answer 1

The Correct Option is A

Bilaterally Symmetrical Animals and Cephalization

• Assertion (A): Bilaterally symmetrical animals are more efficient in seeking food and locating mates. (✔ True)
• Reason (R): Cephalization, the concentration of sensory organs and nerve cells in the anterior region, enhances their ability to locate food and mates. (✔ True)

Since both A and R are true, and R correctly explains A, the correct answer is (A).
