Sulpha drug is which of the following types of drug?

Correct answer: (d) Antibacterial

Explanation

Sulpha (sulphonamide) drugs are antibacterial agents, first used in the 1930s.

They inhibit the enzyme dihydropteroate synthase (DHPS), blocking bacterial folate synthesis.

Antiseptics, analgesics and antipyretics act differently and do not target this bacterial pathway.
