Indirect question to direct speech:

Change	Indirect	Direct	Why
Reporting verb	asked	said to	Asked becomes said to, and the words spoken go inside inverted commas.
Question form	if she wanted	Do you want ...?	If is dropped and the sentence becomes a real question with do and a question mark.
Tense change	wanted	want	The past wanted goes back to the present want, the tense the mother used.
Pronoun change	she	you	The daughter is spoken to, so she becomes you.
Full sentence	She asked her daughter if she wanted ice-cream.	She said to her daughter, “Do you want ice-cream?”

Example: He asked me if I liked tea. → He said to me, “Do you like tea?”

Why the Other Options are Incorrect?

Option 2: She said to her daughter, "Did she want ice-cream?" — Incorrect.

• It keeps "she", although the mother is speaking to her daughter.
• It keeps the past tense instead of going back to the present.

Option 3: She said to her daughter, "Did she wanted ice-cream?" — Incorrect.

• After did, the verb must be in the base form (want), not "wanted".
• The pronoun "she" is also wrong.

Option 4: She said to her daughter, "Does she want ice-cream?" — Incorrect. The tense is right, but "she" should be "you", since the daughter is the person spoken to.
