Chose the correct question tag?

The correct option is: He said that, didn't he?

Step-by-Step Explanation:

1. Understanding Question Tags:
A question tag is a very short clause added to the end of a statement to turn it into a question or to ask for confirmation. The basic rule for forming question tags is:
- If the main statement is positive, the question tag must be negative.
- If the main statement is negative, the question tag must be positive.

2. Analyzing the Correct Option ("He said that, didn't he?"):
- The main statement is "He said that". This is a positive statement in the simple past tense.
- Because the statement is positive, we need a negative tag.
- The verb "said" is in the simple past tense, so we use the auxiliary verb "did" (in its negative form, "didn't") for the tag.
- The subject pronoun "he" is kept in the tag.
- Combining these gives "didn't he?", making the sentence grammatically correct: "He said that, didn't he?"

3. Why the other options are incorrect:
- "He said that, did he?": The statement "He said that" is positive, so it requires a negative tag ("didn't he?"), not a positive one ("did he?").
- "She didn't do that, didn't she?": The statement "She didn't do that" is negative, so it requires a positive tag ("did she?"), not a negative one ("didn't she?").
- "They will come, will they?": The statement "They will come" is positive, so it requires a negative tag ("won't they?"), not a positive one ("will they?").
