While she _ TV, the lights went out.
Correct answer: B. Was watching
- A. Watched
- B. Was watching
- C. Had watched
- D. Watches
Explanation
The correct answer is 'was watching' because the sentence describes an ongoing action in the past that was interrupted by another action (the lights going out). The word 'while' indicates a continuous action, which the past continuous tense ('was watching') effectively conveys. The other options do not appropriately match the sequence and nature of events: 'watched' implies a completed action, 'had watched' suggests the action was completed before another past action, and 'watches' incorrectly uses present tense.
