Assertion (A) states that in cockroaches, the gizzard is the same as teeth and the crop is the same as the stomach of humans. This statement is true.

Reason (R) states that the gizzard is a tooth-like structure that helps in grinding of food and the crop acts as a reservoir for storing food. This statement is also true, but it is not the correct explanation for why the gizzard is considered the same as teeth and the crop is considered the same as the stomach of humans.

In cockroaches, the gizzard is a muscular structure that contains chitinous plates and helps in grinding the food that has been ingested. The chitinous plates in the gizzard act like teeth to help break down the food into smaller pieces. However, it is not accurate to say that the gizzard is the same as teeth. Similarly, the crop in cockroaches is a sac-like structure that acts as a temporary storage site for food before it enters the midgut for digestion. While it serves a similar function to the human stomach, it is not the same as the stomach.

Therefore, since both Assertion (A) and Reason (R) are true, but the reason is not the correct explanation for the assertion, the correct answer is (2).
