Select the option that expresses the given sentence in indirect speech. He said, "It's been raining since last night."

Explanation

The correct answer is: He said that it had been raining since the night before. Key Points In Direct-Indirect speech, If the reporting speech is in the present perfect continuous tense then the reported speech will be changed into the past perfect continuous tense. In this question, the reporting speech is written in the present perfect continuous tense. The structure is:subject + is/has/have + been + verb (ing) + object. So, the reported speech must be in the past perfect continuous tense. The structure is: subject + had + been + verb (ing) + object. Example - He said, "I have been living in Delhi." (Direct) He said that he had been living in Delhi. (Indirect) Therefore, except option 2, no other options are fulfilling the exact rules for Direct-Indirect speech. Hence, the correct answer is option 2 . The correct indirect speech is:He said that it had been raining since the night before.
