Step 1: Understanding narration conversion.
The given sentence “He requested me to keep the door open” is in indirect speech. To change it into direct speech, we reverse the process — replacing “requested me to” with “said to me, ‘Please…’”
Step 2: Identifying the reporting verb.
The reporting verb “requested” corresponds to a polite request in direct speech using “Please.”
Step 3: Analyzing the options.
- (a) He said to me, "Please keep the door open." — Correct; expresses a polite request.
- (b) He says... — Incorrect tense (present).
- (c) He will say... — Incorrect future tense.
- (d) He said... "Do not keep..." — Opposite meaning (negative command).
Step 4: Grammar note.
Indirect: “requested me to…” → Direct: “said to me, ‘Please…’”
Step 5: Conclusion.
Thus, the correct direct speech form is “He said to me, ‘Please keep the door open.’”
