Read the following excerpt from "1 sell a dog' by mark twain:
the general looked even more surprised than before, and for a moment he couldn't seem to find his voice: then he said, "do you mean to tell me that you were selling another man's dog-and knew it? " what is the role of the idiom in this sentence?

a. to communicate the general's anger at being duped by twain
b. to include a line of dialogue that makes the scene more lifelike
c. to show that the general had a difficult time eaying something
d. to inject humor by showing that the general had developed laryngitis

C. To show that the General had a difficult time saying something.

Explanation:

In this excerpt, Twain uses the expression "to find his voice." This is an idiom that means that the general could not speak. This is Twain's way to say that the General had a difficult time saying something. This is likely a consequence of the fact that the General is in shock due to the actions of the man.
