What do vitamin C, A, and E all have in common
A
nothing
B
Act as antioxidants
C
Blood clotting support
D
Brain function
Explanation: 

Detailed explanation-1: -Vitamin C prevents the pro-oxidant activity of vitamin E by decreasing the activity of -tocopheroxyl radical to -tocopherol, thereby acting as a co-antioxidant and further contributing to increased total antioxidant status and reduced oxidative stress.

Detailed explanation-2: -Vitamins A, C and E have antioxidant properties. This means they can override harmful molecules, known as free radicals, which are produced within your cells and which may cause tissue damage or disease.

Detailed explanation-3: -As an antioxidant, vitamin C provides protection against oxidative stress-induced cellular damage by scavenging of reactive oxygen species, vitamin E-dependent neutralization of lipid hydroperoxyl radicals, and by protecting proteins from alkylation by electrophilic lipid peroxidation products.

Detailed explanation-4: -Vitamin E is a fat-soluble vitamin with several forms, but alpha-tocopherol is the only one used by the human body. Its main role is to act as an antioxidant, scavenging loose electrons-so-called “free radicals”-that can damage cells.
