The correct option is E Both assertion and reason are wrong statements
Assertion
Food preservatives are not the only chemicals that are added to food items. There are also natural and artificial sweetening agents (for use of diabetic patients to lower their calorie intake) which are added to food.
So, assertion is wrong.
Reason:
Food preservatives only prevent foods from spoilage caused by micro-bacterial growth. It does not increase the nutritive value of the food.
So, reason is wrong statement.
Hence, both assertion and reason are wrong statements.
