Choose the correct Passive Voice for the sentence- 'He was driving th…

The correct answer is Option (4) → The car was being driven by him.

Passive of the past continuous:

Change	Active	Passive	Why
Object becomes subject	the car	The car	“The car” moves to the front.
Tense kept	was driving	was being driven	The past continuous stays, as was/were + being + past participle: “was driving” becomes “was being driven”.
Agent (by ...)	He	by him	The doer “he” goes to the end as by him.
Full sentence	He was driving the car.	The car was being driven by him.

Example: The workers were painting the wall. → The wall was being painted by the workers.

Why the Other Options are Incorrect?

Option 1: The car was driven by him. — Incorrect. It drops "being", so it is the passive of the simple past ("He drove the car"), not of the past continuous.

Option 2: The car was driving him. — Incorrect. It is still active and makes the car the driver.

Option 3: The car was been driven by him. — Incorrect. "Was been" is not an English verb form. The continuous passive needs "being".

Contrast: "was being driven" is the passive of the past continuous. "Was driven" is the passive of the simple past.
