The correct answer is Option (2) → The Principal warned the student that he would suspend him if he didn't behave properly in the class.

Statement (a warning) in indirect speech:

Change	Direct	Indirect	Why
Reporting verb	said to	warned	The words are a threat of punishment, so “said to” becomes warned.
Joining word	“ ” (inverted commas)	that	The joining word is that.
Tense change	will, don't	would, didn't	The reporting verb is in the past: will becomes would, and don't becomes didn't.
Pronoun change	I, you	he, him / he	“I” (the Principal) becomes he. “You” (the student) becomes him / he.
Full sentence	The Principal said to the student, “If you don't behave properly in the class, I will suspend you.”	The Principal warned the student that he would suspend him if he didn't behave properly in the class.

"In the class" stays.

The if-clause stays as a condition.

Example: Mother said to me, “If you touch the stove, you will burn yourself.” → Mother warned me that I would burn myself if I touched the stove.

Why the Other Options are Incorrect?

Option 1: The Principal requested the student to behave properly in the class or else he will be suspended. — Incorrect.

• A threat is not a request.
• "Will" is not changed to would.

Option 3: The Principal told the student that he will suspend him because of his mis behaviour. — Incorrect.

• The condition "if he didn't behave" becomes a reason ("because of"), as if the student had already misbehaved.
• "Will" is not changed to would.

Option 4: The Principal advised the student to behave properly is the class. — Incorrect.

• It drops the threat of suspension altogether.
• "Is the class" is a mistake for "in the class".
