Choose the option which best expresses the same sentence in reported…

The correct answer is Option (3) → Kavita said that she would tell Rahini she had met me.

Direct to indirect speech:

Change	Direct	Indirect	Why
Reporting verb	said, “ ”	said that	“Said” stays, followed by “that”.
Pronoun change	I, you	she, me	“I” (Kavita) becomes “she”. “You” (the person Kavita spoke to, now reporting) becomes “me”.
Tense change	’ll tell (will tell), met	would tell, had met	Tenses move one step back because the reporting verb is in the past: “’ll tell” (will tell) becomes “would tell”, and “met” (simple past) becomes “had met” (past perfect).
Full sentence	Kavita said, “I’ll tell Rahini I met you.”	Kavita said that she would tell Rahini she had met me.

Example: He said, “I will finish the work.” → He said that he would finish the work.

Why the Other Options are Incorrect?

Option 1: Kavita said that she will tell Rahini she met me. — Incorrect. Neither tense is changed: "will" should become "would" and "met" should become "had met".

Option 2: Kavita said that she would tell Rahini she met me. — Incorrect. "Will" is changed, but "met" stays in the simple past instead of "had met".

Option 4: Kavita told that she would tell Rahini she had met me. — Incorrect. "Told" needs an object (told me, told him). "Told that" without one is wrong.

Contrast: said takes no object (said that ...). Told needs one (told me that ...).
