None of these is true. (Ans e.)

Explanation:

C) Inhaled chemicals can irritate the throat or nose, damage the lungs, and enter through the lung to the bloodstream.

A) Skin is not impermeable in nature.

B) It is not safe to smoke around hazardous chemicals, as long as you wear gloves, because people can carry hazardous chemicals from cigarette smoke then releasing those compounds into non-smoking environments.

D) Alkaline can denature proteins, and they also break down fats in a process which is known as saponification. Burns from alkalines worse than burns from acids.
