In the given sentence, identify the part which contains an error.
John, a Britisher, was married with an Indian woman.

Correct option is C

The correct answer is (c) was married with.
The phrase “married with” is incorrect in standard English. The correct preposition used with married is to, so the correct sentence is: John, a Britisher, was married to an Indian woman.
• Grammatical rule involved (English):
The adjective/verb married is followed by the preposition to (married to someone). The preposition with is not used to indicate marriage.
• व्याकरण नियम (Hindi):
Married शब्द के साथ सही preposition to होती है।
Married with का प्रयोग विवाह के संदर्भ में गलत माना जाता है।
• Meanings / role of the other options:
• (a) John — correct subject.
• (b) a Britisher — correct appositive phrase.
• (d) an Indian woman — correct object phrase.
Thus, the correct option is (c).
