The frog’s tongue is anchored in the very front. why is it anchored this way?

Frogs, unlike humans, have tongues that are anchored at the front of their mouths because when they catch an insect it throws its tongue out of its mouth and and wraps it around the insect and then brings it back to their mouth for consumption.

Ihaven't done that yet, so no idea,but this is not the right place to ask

The answer is b. hope this !
