Question

multiple choice question
the characteristic of immunity describing how it is directed against a particular pathogen is ______.

○ memory
○ immunity
○ specificity

Explanation:

To solve this, we analyze each option:

• "memory" in immunity refers to the ability to remember past infections, not direction against a specific pathogen.
• "immunity" is a general term, not a characteristic describing direction against a particular pathogen.
• "specificity" in immunity means the immune response is directed against a particular (specific) pathogen.

Answer:

C. specificity (assuming the options are labeled A: memory, B: immunity, C: specificity; if labels differ, adjust but the correct option text is "specificity")
