Change the following sentence to Indirect Speech.
He said to her, "I've been waiting here in the queue for over an hour".

- The direct speech given is in the present progressive form (have + been +ing)
- According to the rules, present perfect progressive (have +been+ ing) changes into past perfect progressive (had + been +ing);
- thus it can be seen only in option 2 which makes it appropriate conversion.
- Moreover, after changing 'said to her' into 'told her';
- the first-person pronoun ('I') should be changed to the third-person pronoun ('He') according to the rules.
- Hence, from the above explanation, the correct answer will be:
- "​He told her that he had been waiting there in the queue for over an hour."
