Select the most appropriate Direct form of the sentence - "Meetu sugg…

The correct answer is Option (4) → (D) Only

"Suggested ... that they should" reports a proposal that includes both the speaker and the listener.

• Reporting verb: in direct speech "suggested to" becomes said to.
• Tense change: none. "Should go" is not kept. Such a proposal is made with Let us + base verb.
• Pronoun changes: "they" (Meetu and her friend) → us.
• Words of nearness (time and place): none in this sentence.

(A) Meetu said to her friend, "I shall go for a picnic". — Incorrect.

• "I shall go" is about Meetu alone and states a plan.
• The original suggests that both of them go.

(B) Meetu says to her friend, "Let us go for a picnic". — Incorrect.

• "Let us" is right, but the reporting verb "says" is in the present.
• The original "suggested" is past, so it must be "said".

(C) Meetu suggested to her friend, "We should go for a picnic". — Incorrect.

• In direct speech the reporting verb is said to.
• A shared suggestion is expressed by Let us, not by keeping "should" from the indirect form.

(D) Meetu said to her friend, "Let us go for a picnic". — Correct.

• Said to in the past and Let us for a suggestion that includes both friends.
• Example: Ravi suggested to me that we should play chess. → Ravi said to me, "Let us play chess."

(E) Meetu says to her friend, "We have to go for a picnic". — Incorrect.

• "Says" is in the wrong tense, and "have to" expresses compulsion, not a suggestion.
