Options:

Only statement I is correct.

Only statement II is correct.

Both statements I and II are correct.

Both statements I and II are incorrect.

Correct Answer:

Only statement II is correct.

Explanation:

The correct answer is Option (2) –Only statement II is correct.

Statement I: The body of a frog is divisible into head, trunk, neck, and tail. This statement is incorrect. The body of a frog is typically divided into two main regions: the head and the trunk. Frogs do not have a distinct neck or tail. The head contains structures such as the eyes, nostrils, and mouth, while the trunk includes the body and limbs.

Statement II: Male frogs can be distinguished by the presence of vocal sacs and a copulatory pad on the first digit of the forelimbs. This statement is correct. Male frogs can be distinguished from females by certain features. Frogs exhibit sexual dimorphism. Male frogs can be distinguished by the presence of sound producing vocal sacs and also a copulatory pad on the first digit of the fore limbs which are absent in female frogs.
