Select the option that expresses the given sentence in active voice.
The new building was being constructed by the construction workers.

Correct option is A

Active Voice: In Active voice the subject is the one doing the action.
Passive Voice: In Passive voice the subject is the recipient of the action.

The correct active voice of the given sentence is (a) The construction workers were constructing the new building.

The given sentence is in past continuous passive voice:

Passive voice structure: Object + was/were + being + V3 + by + subject

→ "The new building was being constructed by the construction workers."

To convert into active voice:

Structure of Active Voice in Past Continuous: Subject + was/were + V1 + ing + object

→ "The construction workers were constructing the new building."

Other options are incorrect because:

· (b) "had been constructing" is past perfect continuous, not past continuous.

· (c) "has being" is grammatically incorrect (should be "is being").

· (d) "is being" – changes tense to present continuous passive, not matching the original.
