Find the incorrect part of the sentence:
She married with a doctor.

Correct option is A

Option (a) contains an error.
Detailed explanation: The verb marry is a transitive verb and doesn’t take the preposition “with” in standard English when used in the active voice. Correct usage: “She married a doctor.”
Grammatical rule used: Transitive verb “marry” takes a direct object: S + married + O. Use “married to” only in passive/adjectival structures (e.g., She is married to a doctor).
Example:
• Correct (active): She married a doctor.
• Correct (linking/adjectival): She is married to a doctor.
Information booster / exceptions:
• In certain dialects/informal speech, “marry with” occurs, but for exams/standard usage, avoid “with” after marry in active constructions.
