Answer :
The answer is A
In a sentence written in passive voice, the subject receives the action expressed in the verb. In other words, the subject is acted upon. The agent performing the action may appear in a prepositional phrase (such as by the government) or may be omitted.
Active voice is often preferable to passive voice because sentences in active voice are generally clearer and more direct.
The following sentence from the passage is written in passive voice:
"In 1964, Mandela was sentenced to life in prison for his work against the South African government."
The subject (Mandela) receives the action (was sentenced). The agent or doer of the action is not named.
