Answer is Wrong!
Answer is Right!
The correct answer is C. The convict requested that he be allowed to speak freely.
A suggestion is a tentative proposal or idea. A request is a formal or informal demand for something. A proposal is a plan or scheme put forward for consideration.
In this case, the convict is using the word “please” to make a polite request. He is not suggesting or proposing that he be allowed to speak freely, he is asking for permission.
