it is not C because burning of candle is reversible. I think answer is B

Ans 3:

Class : Class 9
Hey, the answer is C only. Because in burning of candle both melting and burning of wax is included right? Ya, so melting of wax is physical change (wax is still wax) and burning of wax is chemical change (wax turns to smoke). And both of these are irreversible. Now see an example. During Diwali we light tea lights, those small, circular candles, right? Have you ever observed it? First the wax melts into liquid wax, then if you don't blow the flame away, the wax burns away! These are CANDLES after all right? So this is how burning of candle is physical, chemical and irreversible change. This answer is written WITHOUT use of any website. Plz consider this as solution. SOF if you could add this as solution could you do that?
