Solution

The correct option is D
Macropus

Pinnae or external ears are present in mammals. Macropus (kangaroo) is a mammal. Hyla (tree frog) is an amphibian, while Chameleon (tree lizard) and Testudo (tortoise) are reptiles. In both these groups, tympanum represents the ear, and pinnae are absent.
