Select the option that expresses the given sentence in active voice. The painting was admired by art enthusiasts from around the world.

Correct — B. The given sentence is passive: 'was admired' is the verb, 'the painting' is the grammatical subject, and 'by art enthusiasts from around the world' names the agent.

To make it active, the agent becomes the subject and the old subject becomes the object.
Art enthusiasts from around the world + admired + the painting.

The tense is the deciding line. Was admired is simple past, so the active verb must be admired, simple past — which is what option (b) prints, with nothing else altered.

Why the others are wrong

• (a)
  Art enthusiasts from around the world have admired the painting. — The direction of the conversion is right, but have admired is present perfect while the given passive is simple past. Changing voice does not license a change of tense.
• (c)
  The painting was being admired by art enthusiasts from around the world. — This is still passive — was being admired only shifts the aspect to past continuous. The painting is still the subject, so the sentence has not been made active at all.
• (d)
  The painting has been admired by art enthusiasts from around the world. — Has been admired is present perfect passive. It leaves the sentence passive and moves the tense as well, so it misses on both counts.

Passive-to-active conversion has two mechanical steps and one rule that guards them.

Step one: the agent of the passive — the phrase after 'by' — becomes the subject. Step two: the passive subject becomes the object.

The guard is that the tense does not change. Simple past passive (was or were + past participle) becomes simple past active. Present perfect passive (has been + past participle) becomes present perfect active.

The three wrong options here are built on that guard: one keeps the direction and moves the tense, and two leave the sentence passive.

Key facts

• Simple past passive (was or were + past participle) converts to simple past active.
• Changing the voice of a sentence never changes its tense.
• The agent of a passive sentence is the noun phrase introduced by 'by'.

Common traps

• Choosing a present-perfect active because it sounds more finished than the plain past.
• Marking an option that is still passive because it reads smoothly.
