Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The digestive tract of Columba and Struthio has additional chambers like crop and gizzard. Reason (R): All homoiothermous animals possess a crop and gizzard to facilitate the rapid digestion required for high energy demands. In the light of the above statements, choose the most appropriate answer f
Options
- ABoth (A) and (R) are correct and (R) is the correct explanation of (A)
- BBoth (A) and (R) are correct but (R) is not the correct explanation of (A)
- C(A) is correct but (R) is not correct
- D(A) is not correct but (R) is correct
Correct answer
C. (A) is correct but (R) is not correct
Step-by-step solution
Columba (pigeon) and Struthio (ostrich) belong to Class Aves. The digestive tract of birds has additional chambers, the crop and gizzard, making the Assertion correct. Homoiothermous (warm-blooded) animals include both birds (Class Aves) and mammals (Class Mammalia). While birds possess a crop and gizzard, mammals do not have these additional chambers in their digestive tract. Therefore, the Reason is incorrect. Answer: (A) is correct but (R) is not correct
