Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. A new hospital is being built in the city by them.
Passive Voice Rule for Present Continuous:
Active: Subject + is/am/are + verb-ing + object
Passive: Object + is/am/are + being + past participle + by + subject
Applying this:
Active: They are building a new hospital.
Passive: A new hospital is being built by them.
The other options are incorrect because:
"was built" (past simple) – wrong tense.
"has been built" (present perfect) – wrong tense.
"will be built" (future) – wrong tense.
