Explanation:

To retract means to withdraw a statement  or accusation. The word "goon" is used to refer to a violent criminal who is paid to hurt or threaten people and in this context, the concerned person will be forced to withdraw the complaint because of fear. Thus, "scare" is the appropriate word for the blank. The infinitive "to" should be followed by the base form of the verb. Hence, options D and E can be eliminated."Goons" is a plural subject, thus, a singular verb "stalls" cannot be used. "Render" is incorrect in the given context.

Thus, option A is the correct answer.
