Choose the correct question tag?

The correct answer is Option (1) → He said that, didn't he?

Detailed reasoning:

1. He said that, didn't he?

   • Main clause: He said

   • It is a positive statement, so the tag must be negative: didn't he?

   • This follows the correct question-tag rule.

   • Therefore, this option is correct.

2. He said that, did he?

   • The statement is positive, so the tag cannot be positive.

   • Incorrect.

3. She didn't do that, didn't she?

   • Statement is negative (didn't), so the tag must be positive (did she?).

   • Incorrect.

4. They will come, will they?

   • Statement is positive (will), so the tag must be negative (won’t they?).

   • Incorrect.

Thus, the correct question tag is:

He said that, didn't he?
