If they _____ that the weather was going to be so bad, they wouldn't have gone to the beach.

  • A. knew
  • B. had known
  • C. knew
  • D. could have known
Correct Answer: B

Rationale: The correct answer is 'B: had known.' In this conditional sentence, the past perfect tense is required to indicate that knowing about the weather should have happened before going to the beach. 'Knew' (choice A and C) is in the simple past tense, which doesn't convey the sequence of events accurately. 'Could have known' (choice D) is incorrect as it implies a possibility of knowing in the past, but it doesn't fit the context of the sentence where the emphasis is on prior knowledge before going to the beach.
