Select the sentence that is grammatically correct:

The correct answer is Option (3) → Our music teacher is married to a tabla player from Varanasi.

“Married to” someone:

• We say a person is married to someone, not “married with” someone.
• So “is married to a tabla player” is correct.

Why the Other Options are Incorrect?

Option 1: A pair of new sandals were lying near the steps of the temple. — Incorrect. The subject is “a pair”, which is singular. So the verb must be singular.
Corrected: A pair of new sandals was lying near the steps of the temple.

Option 2: I will call you when the train will reach Itarsi tonight. — Incorrect. After “when”, a future action takes the simple present, not “will”.
Corrected: I will call you when the train reaches Itarsi tonight.

Option 4: This small water pump is capable to fill our roof tank in ten minutes. — Incorrect. “Capable” takes “of” + the -ing form of the verb.
Corrected: This small water pump is capable of filling our roof tank in ten minutes.
