What does the term "sulfa drug" refer to?

  1. Mild debarment from a privilege

  2. Inhibition of bacterial growth

  3. Secretion of perspiration

  4. Antibacterial capability against bacteria requiring PABA

The correct answer is: Antibacterial capability against bacteria requiring PABA

Sulfa drug is a term used to refer to antibiotics that contain sulfonamides. These types of drugs are characterized by their ability to inhibit the growth of bacteria by interfering with folic acid production. Option A is incorrect as it is not related to the concept of "sulfa drug". Option C is also incorrect as it relates to the secretion of sweat rather than antibiotic properties. Option B is partially correct as it mentions inhibition of bacterial growth, but does not specify the type of bacteria that sulfa drugs target - those requiring PABA. Therefore, option D is the correct answer.
