The correct option is D

both B and C

The correct option is D.

Explanation of the correct option :

2. Some methods of food preservation are pasteurization, preservation by common salt, sugar, vinegar, cold storage, etc.
3. Food preservatives such as common salt, sugar, vinegar, etc. reduce the water content and thus help in controlling the growth of the microorganisms, thus increasing the self-life and preserving food for a long time.
