Correct option is B
Option (b) contains an error.
· The phrase
"She use to" is incorrect. The correct phrase should be
"She used to." The past tense form "used to" is required to indicate a habitual action in the past.
·
Grammatical rule used: "Used to" is the correct phrase to describe an action that was regularly performed in the past but is no longer done. The base form "use" is incorrect in this context.

Example: "He used to play the piano when he was younger." Here, "used to" correctly indicates a past habitual action.
