Solution

The correct option is D Both statements 1 and 2 are incorrect.
Low temperature preserves the enzymes in their inactive state. Therefore it is used in preservation of foods inside cold storage. Low temperature present inside cold storage prevents spoilage of food.
High temperature destroys enzymes by causing their denaturation, This occurs at $50^{o} C$ or so. In between the minimum and maximum temperature the reaction velocity doubles for every $10^{o} C$ in temperature (general rule of thumb).
Both statements 1 and 2 are incorrect.
