Select the option that is grammatically correct:

The correct answer is Option (2) → The reason our cricket match was called off was that the pitch was still wet from the rain.

“The reason ... is that”:

• “The reason” already means “why”. So it is followed by is / was that, not “is / was because”.
• Here the sentence says The reason ... was that the pitch was still wet. “That” gives the reason.

Why the Other Options are Incorrect?

Option 1: My uncle returned yesterday evening home from Pune. — Incorrect. The option says “returned yesterday evening home”. “Home” tells the place and must come straight after the verb “returned”. The time comes after the place.
Corrected: My uncle returned home from Pune yesterday evening.

Option 3: The electrician arrived until four, so the fans stayed off all afternoon. — Incorrect. The option says “arrived until four”. Arriving happens at one moment, so it cannot go on “until” a time. We use “did not arrive until”.
Corrected: The electrician did not arrive until four, so the fans stayed off all afternoon.

Option 4: On no account you should leave the gas stove on when you go out. — Incorrect. The option says “On no account you should”. When a sentence starts with “On no account”, the helping verb comes before the subject.
Corrected: On no account should you leave the gas stove on when you go out.
