Sources of vitamin c include all but a. citrus fruitsb. green leafy vegetablesc. meat and fishd. tomatoes and green peppers

The correct answer is C. Sources of vitamin C include all but meat and fish.

Explanation:

Vitamin C is the common name for L-ascorbic acid, which is a vitamin for humans and certain organisms. In addition, it may mean dehydroascorbic acid (DHA). DHA can be converted into L-ascorbic acid in animals.

Vertebrates need L-ascorbic acid (or DHA). For most species, however, it is not a vitamin, as most are capable of producing it. Humans, other primates and guinea pigs, among others, do not produce ascorbic acid, so they should get it from food.

L-ascorbic acid and DHA are most abundant in fruits (mostly citrus such as orange or lemon), berries and vegetables. They are hardly found in cereals, nuts, other seeds or vegetable oils. They are scarce in animal foods, but can be abundant in the liver and other organs.
