- Option 2: "Seven people were rescued from the fire" is correct. The sentence uses proper past tense and is grammatically accurate.

Therefore, the correct answer is option 1.

Additional Information

- Past Tense Usage:
- Past tense is used to describe actions that have already been completed.
- Example: "She walked to the park yesterday."
