Choose the correct transformation of the given sentence in Indirect S…

The correct answer is Option (4) → Mrs Sharma asked the gardener if he would water her plants while she was in Goa.

Changing a yes/no question into indirect speech:

Change	Direct	Indirect	Why
Reporting verb	said to the gardener	asked the gardener	Mrs Sharma puts a question. So “said to” becomes “asked”.
Joining word	“ ” (quotation marks)	if	The question is answered with yes or no. So “if” (or “whether”) joins it.
Word order	Will you water	he would water	The question order changes to the plain order. The subject “he” comes before “would”, and the question mark goes.
Pronoun change	you, my, I	he, her, she	The gardener is spoken to, so “you” becomes “he”. Mrs Sharma is the speaker, so “my” becomes “her” and “I” becomes “she”.
Tense change	will, am	would, was	After the past “said”, “will” becomes “would” (would + base form (V1)). The simple present “am” becomes the simple past “was”. The verb “be” in the simple present is am / is / are. The verb “be” in the simple past is was / were.
Full sentence	Mrs Sharma said to the gardener, “Will you water my plants while I am in Goa?”	Mrs Sharma asked the gardener if he would water her plants while she was in Goa.

“Can” in a question becomes “could” in the same way. Example: Raj said to me, “Can you swim?” → Raj asked me if I could swim.

Why the Other Options are Incorrect?

Option 1: Mrs Sharma asked the gardener if he will water her plants while she was in Goa. — Incorrect. “Will” is kept. After the past “said” it must become “would”.

Option 2: Mrs Sharma asked the gardener if would he water her plants while she was in Goa. — Incorrect. “Would he” keeps the question word order. In a reported question the subject comes first: “he would”.

Option 3: Mrs Sharma asked the gardener that he would water her plants while she was in Goa. — Incorrect. “That” joins a statement. A yes/no question is joined with “if” or “whether”.
