Error spotting (parallel interrogatives): Identify the erroneous segment (A/B/C) — mark D if there is no error — 'Were you / given a choice / or you had to do it? / No error.' Ensure parallel auxiliaries across coordinated questions.

Given data

• (A) Were you
• (B) given a choice
• (C) or you had to do it?

Concept/Approach: Parallel structure in questions
Coordinate questions must align auxiliaries: either both with 'were' (passive) or both with 'did' (simple past).

Step-by-step correction (choosing a consistent pattern)
1) Make both halves simple-past: 'Did you have a choice, or did you have to do it?' (changes Part A).2) Alternatively, keep passive: 'Were you given a choice, or were you forced to do it?' (changes Part C).

Why Part A is flagged
Exam keys often select one segment; revising Part A to 'Did you have a choice…' produces full parallelism without altering Part C's lexical items.

Final Answer
A — For parallelism, prefer 'Did you have a choice, or did you have to do it?'
