Select the option that expresses the given sentence in direct speech.…

The correct answer is Option (3) → Ankit said to his mother, “My school will remain closed tomorrow because of this cyclone warning.”

Changing a statement from indirect back into direct speech:

Change	Indirect	Direct	Why
Reporting verb	told his mother	said to his mother	“Told” goes back to “said to” before the spoken words.
Joining word	that	“ ” (quotation marks)	“That” is dropped. The spoken words go inside quotation marks.
Pronoun change	his	My	Ankit is the speaker. In his own words “his school” becomes “my school”.
Tense change	would remain	will remain	“Would” came only from the past “told”. Going back, it returns to “will” (will + base form (V1)).
Time and place words	the next day, that	tomorrow, this	Ankit spoke a day before the school was to close. So “the next day” goes back to “tomorrow” and “that” goes back to “this”.
Full sentence	Ankit told his mother that his school would remain closed the next day because of that cyclone warning.	Ankit said to his mother, “My school will remain closed tomorrow because of this cyclone warning.”

“The day before” goes back to “yesterday” in the same way. Example: Sonal told me that she had met Priya the day before. → “I met Priya yesterday,” Sonal said to me.

Why the Other Options are Incorrect?

Option 1: Ankit said to his mother, “My school remained closed tomorrow because of this cyclone warning.” — Incorrect. “Remained” is in the past, but “tomorrow” is in the future. “Would remain” goes back to “will remain”.

Option 2: Ankit said to his mother, “My school will remain closed the next day because of this cyclone warning.” — Incorrect. “The next day” is kept inside the quotation marks. In his own words Ankit says “tomorrow”.

Option 4: Ankit said to his mother, “His school will remain closed tomorrow because of this cyclone warning.” — Incorrect. The pronoun “his” is not changed. In his own words Ankit says “my school”.
