Change the following sentence into Indirect Speech:

Abhinav said, "Your father will be terribly worried, Rajiv".

Abhinav told Rajiv that his father would be terribly worried.

The correct answer is Option (4) → Abhinav told Rajiv that his father would be terribly worried.

Explanation:
- The original sentence is in Direct Speech, where Abhinav directly addresses Rajiv and mentions what he said.
- In Indirect Speech, we report what someone else said without quoting their exact words. We typically use reporting verbs such as "told," "said," or "informed."
- The pronouns are adjusted to fit the new context. "Your" changes to "his" to match Rajiv, the person being spoken to.
- "Will" changes to "would" to shift the tense back one step in reported speech.
- Therefore, the correct transformation is: "Abhinav told Rajiv that his father would be terribly worried." This accurately conveys the original meaning in Indirect Speech.
