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

The correct answer is Option (1) → The new neighbour asked Sana where she bought fresh fish in that colony.

Changing a “Where ...?” question into indirect speech:

Change	Direct	Indirect	Why
Reporting verb	said to Sana	asked Sana	The neighbour puts a question. So “said to” becomes “asked”.
Joining word	“ ” (quotation marks)	where	The question word “where” itself joins the question. No “that” is added.
Word order	do you buy	she bought	The question becomes a plain statement. “Do” is dropped, and the subject “she” comes before the verb.
Tense change	do ... buy	bought	“Do ... buy” is in the simple present. The simple present is formed with the base form (V1), or V1 + s / es with he, she, it. After the past “said” it becomes the simple past “bought”. The simple past is formed with the past form of the verb (V2).
Pronoun change	you	she	Sana is spoken to, so “you” becomes “she”.
Place word	this	that	The words are reported later, so “this colony” becomes “that colony”.
Full sentence	The new neighbour said to Sana, “Where do you buy fresh fish in this colony?”	The new neighbour asked Sana where she bought fresh fish in that colony.

“Does” is dropped in the same way. Example: Papa said to Dev, “What does your coach want?” → Papa asked Dev what his coach wanted.

Why the Other Options are Incorrect?

Option 2: The new neighbour asked Sana where did she buy fresh fish in that colony. — Incorrect. “Did she buy” keeps the question word order. In indirect speech the subject comes first: “she bought”.

Option 3: The new neighbour asked Sana where she had bought fresh fish in that colony. — Incorrect. “Had bought” is the past perfect. “Do ... buy” is in the simple present, so it moves one step back only, to the simple past “bought”.

Option 4: The new neighbour asked Sana that where she bought fresh fish in that colony. — Incorrect. “That where” puts two joining words together. A reported question takes the question word alone.
