Explanation
Correct option is A. The other name of 2,4,6-trinitrophenol is picric acid. It is a yellow, crystalline solid that is highly explosive. It is also a strong acid and can cause severe burns. The name "picric" comes from the Greek word "pikros", which means "bitter". This is because picric acid has a very bitter taste. Picric acid was first synthesized in 1771 by Carl Wilhelm Scheele.

It is also used in some fireworks and as a component of some smokeless powders.

About Alcohols and Phenols
Alcohols are classified as primary, secondary or tertiary and studied through their hydrogen bonding, acidity, oxidation and reactions with active metals, acids and halogenating agents. Phenols require separate treatment because the hydroxyl group is attached to an aromatic ring, making their acidity and electrophilic substitution different from ordinary alcohols.
