A sentence is provided in direct speech. From the four given options, choose the one that most accurately conveys the sentence in its corresponding indirect speech. He asked me, “Did you submit your homework?”

The correct indirect speech is (a) He asked me if I had submitted my homework. Rules of conversion applied: Reporting verb asked requires if/whether for yes-no questions. Tense backshift: Simple Past (did submit) → Past Perfect (had submitted) because the reporting verb is in the past. Interrogative order changes to statement order (subject + verb). Pronoun change: you→ I according to the object me. Question mark is replaced by a full stop. Example for clarity: She asked him, "Did you finish the task?" → She asked him if he had finished the task. Why other options are incorrect: (b) Retains question word order (did I submit), which is incorrect in indirect speech. (c) Fails to backshift the tense (have submitted), violating the sequence of tenses. (d) Uses inverted order (had I submitted), which is not permitted in indirect statements.
