Change the following sentence from Direct Speech to Indirect Speech.
The teacher said to the erring students, “Why don’t you do your homework at home?”

Correct option is C

The correct indirect speech is (c).
Correct indirect sentence:
The teacher asked the erring students why they did not do their homework at home.
Rules of conversion (Direct → Indirect):
· “said to” → asked (because it is an interrogative sentence)
· Question word “why” is retained.
· Do not use auxiliary “did” in indirect questions.
· Pronoun “you” → they.
· Present tense → Past tense ( do → did).
Why other options are incorrect:
· (a) Incorrect use of “that” with a question.
· (b) Wrong word order ( why did they not ).
· (d) Changes the sentence into a command, altering meaning.
