Best Answer Explained in Below-:

The correct choice is C: "when I went there" because it follows standard English grammatical structure, particularly in reported speech. The phrase "He asked me" introduces a subordinate clause that conveys a question that was posed. In this context, when transforming direct speech into indirect speech, the word order must align with grammatical norms.

Option A, "when did I go there," is incorrect because it maintains an interrogative structure that does not fit within the context of reported speech. In reported speech, we typically do not use the auxiliary verb "did" in such constructions.

Option B, "when went I there," is also incorrect due to its unconventional word order, which does not conform to standard English syntax, where the subject typically precedes the verb.

Option D, "that when I did go there," is incorrect for similar reasons. The inclusion of "that" and the use of "did" introduces unnecessary complexity and disrupts the flow of the sentence.

Thus, "when I went there" correctly reflects the appropriate sequence and structure, making it the most grammatically sound option.
