Pawan said to me, "If I hear any news, I'll phone you."

Original Sentence (Direct Speech):
Pawan said to me, "If I hear any news, I'll phone you."

Step-by-step Conversion:
1. Identify the sentence type: This is a conditional sentence (Type 1), which talks about a possible future action.
2. Reporting verb: “said to me” changes to “told me” in indirect speech.
3. Tense changes: In indirect speech, present tense becomes past:
“hear” becomes “heard”
“will phone” becomes “would phone”
4. Pronoun changes: “I” becomes “he” (for Pawan), and “you” becomes “me” (as it is said to “me”).

Correct Sentence:
Pawan told me that if he heard any news, he would phone me.

Correct Answer: Option D

Why other options are incorrect:
Option A: “he will phone me” — ❌ wrong tense; “will” should change to “would” in indirect speech.
Option B: “if he will hear my news” — ❌ incorrect tense and unnatural phrasing.
Option C: “if he had heard” — ❌ changes the meaning; this becomes a Type 3 conditional, which is incorrect here.

Final Answer: Option D – Pawan told me that if he heard any news, he would phone me.
