Ok thank you that article helped, the answer is C

Yes, C. You're welcome.

Of course! I'd be happy to help you better understand this question.

The question is asking about how frogs hear. In order to answer this question, we can use our knowledge about the anatomy of frogs.

First, let's eliminate the options that are unlikely to be correct based on common knowledge. The lining of the mouth and the tongue are not directly associated with hearing in frogs. This leaves us with two options: the tympanum and the nostrils.

The tympanum is a circular membrane located on the frog's head, just behind the eye. It serves as the frog's eardrum and is specifically adapted to detect sound vibrations. The tympanum vibrates when sound waves reach it, which is then transmitted to the inner ear, allowing the frog to hear.

On the other hand, the nostrils of a frog are mainly used for breathing and smelling. While it is true that frogs can detect sound through the sensory cells located near the nostrils, it is not their primary method of hearing.

Given this information, we can conclude that the correct answer is the "tympanum." Frogs hear with their tympanum, which acts as their eardrum.
