No, you are wrong @Arini Das. The correct answer is B. Baking is a method for cooking only whereas canning and drying are methods of preservation. Boiling is a method of cooking as well as preservation so B is the correct answer.

Magnetic separation can only be used in the cases in which one constituent is magnetic and the other is not. In case one Copper is not magnetic and iron is. In the second case Aluminium is not magnetic and Steel is. nIn the third case both the objects gold and the glass marble are non magnetic objects and hence magnetic separation cannot be used in this case. In the last case both Nickel as well as Steel are magnetic and thus magnetic separation cannot be used. So, magnetic separation can only be used in case 1 and case. Hence the answer is A
