Solution

The correct option is D II, IV

A chemical change is a permanent change as the new substance(s) formed have a different composition than the original substance(s).​

  • Condensation is the change of physical state of matter from gas to liquid.​

  • Photosynthesis is a chemical change as it involves a chemical reaction. Carbon dioxide and water combine to form glucose and oxygen.​

  • Evaporation is the change of physical state of matter from liquid to gas.​

  • Cooking is a chemical change wherein the raw material(s) get permanently transformed into cooked food (new substance)​.

  • Melting is the change of physical state of matter from solid to liquid.​

So, the answer is (ii) and (iv).​
