The lady shouted with a loud, shrill voice.

feeble
blunt
muffled
inaudible

The correct answer is A. feeble.

A feeble voice is weak and not loud. A shrill voice is high-pitched and piercing. A blunt voice is direct and to the point. A muffled voice is difficult to hear because it is blocked or covered. An inaudible voice is too quiet to be heard.

In this case, the lady is shouting with a loud, shrill voice. This means that her voice is both loud and high-pitched. This is in contrast to a feeble voice, which is weak and not loud. A shrill voice can be unpleasant to listen to, but it is often used to get attention. In this case, the lady is probably shouting to get someone’s attention.
