Question:

Which of the following is a natural flame retardant?

Options:

Flowers

Skin

DNA

RNA

Correct Answer:

DNA

Explanation:

The correct answer is Option (3) -DNA

Out of the options listed, DNA is the natural flame retardant.

DNA, or deoxyribonucleic acid, contains nitrogen-containing bases. When exposed to heat, these bases decompose and release ammonia gas.
Ammonia gas acts as a flame retardant by diluting the concentration of oxygen around the burning material, making it harder for combustion to continue.
