B Correct answer
Explanation

The DPT vaccine (also called DTP) protects against three bacterial diseases: Diphtheria (Corynebacterium diphtheriae), Pertussis or whooping cough (Bordetella pertussis), and Tetanus (Clostridium tetani). All three causative organisms are bacteria that produce toxins affecting the respiratory system or nervous system. DPT does not target viruses (like polio or measles in other vaccines), fungi, or protozoa.
