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.
