Question

If she had known about the meeting, ___________

• A. she will attend
• B. she would have attended
• C. she would attend
• D. she attends

Answer 1

Answer:

B. she would have attended

For a past condition (if she had known), we use "would have" to describe what could have happened. "Will attend" is future tense, "would attend" is for present or future possibilities, and "attends" is present tense.
