Answer

Answer:

C. a weakened or dead form of a pathogen

Explanation:

Step1: Understand vaccine concept

Vaccines work by stimulating immune - response.

Step2: Analyze each option

Red blood cells carry oxygen, not in vaccines. White blood cells are part of immune system but not main vaccine component. Synthetic dietary supplements are not in vaccines. A weakened or dead pathogen in a vaccine helps body recognize and fight real pathogen later.
