Select the option that expresses the given sentence in active voice. He was given a reward for his contribution by the Governor.

Correct — C. The given sentence is passive: He was given a reward for his contribution by the Governor. Turning it active means promoting the agent and leaving everything else alone.

Agent: by the Governor becomes the subject The governor.
Verb: was given, past simple passive, becomes gave, past simple active.
Objects: he drops back to the indirect object him, and a reward for his contribution stays exactly as it was.

Option (c) makes all three moves and adds nothing: The governor gave him a reward for his contribution.

Why the others are wrong

• (a)
  The governor rewarded him. — Active, but it drops "a reward for his contribution" and swaps the verb give for reward. A voice change has to carry the same content across, not summarise it.
• (b)
  For his contribution, he was rewarded by the governor. — Still passive — was rewarded by the governor. Moving a phrase to the front reorders the sentence without touching its voice.
• (d)
  Rewarded by the governor, as he contributed along. — Rewarded by the governor is a past-participle phrase, not an active clause, and "as he contributed along" is not idiomatic English. It is not a voice conversion at all.

A voice-change item is a mechanical rewrite, not a rewording. Three things move and nothing else may change.

The agent in the by-phrase becomes the subject. The passive verb, be plus past participle, becomes an active verb in the same tense. The old subject becomes an object.

This sentence carries two objects because give is ditransitive: you give someone something. The passive promoted the indirect object to subject as He, so reversing it puts him back after the verb with a reward still in place.

Key facts

• A voice change keeps the tense: was given is past simple, so the active verb is gave.
• Give is ditransitive, so its passive can promote either object: He was given a reward, or A reward was given to him.
• Reordering a passive sentence does not make it active, because the verb form has to change.

Common traps

• Choosing the shortest active option and quietly losing part of the sentence.
• Accepting a reordered passive as active because the agent now appears early.
• Changing the tense along with the voice, for example turning was given into has given.
