Choose the correct option to complete the following sentence.

Sohan said he regretted that he _________.

had acted so hastily.

The correct answer is Option (2) - had acted so hastily.

The correct option to complete the sentence is:

✅ had acted so hastily.

Explanation:

In reported speech, when expressing regret about a past action, the past perfect tense is used to indicate that the action occurred before the moment of speaking. Therefore, "he had acted so hastily" is the correct choice.

The other options are incorrect for the following reasons:

• "has acted so hastily." (Incorrect) – This is present perfect tense, which does not fit the context of reporting a past regret.
• "was acting so hastily."  (Incorrect) – This suggests an ongoing action rather than a completed one.
• "did the act hastily."  (Incorrect) – This is grammatically awkward and does not appropriately convey the sense of regret.
