Question

multiple choice question
when the body acquires antibodies from another person or an animal that has developed its own immunity to the pathogen, this is what type of immunity?

• cellular
• passive
• active

Explanation:

To determine the type of immunity, we analyze each option:

• Cellular immunity: Involves immune cells (like T - cells) directly attacking pathogens, not about acquiring antibodies from external sources. So this is incorrect.
• Passive immunity: Defined as the acquisition of antibodies from an external source (another person or animal with immunity) rather than the body producing its own antibodies. This matches the description in the question.
• Active immunity: Occurs when the body's immune system is stimulated to produce its own antibodies (e.g., through infection or vaccination), which is not the case here. So this is incorrect.

Answer:

B. Passive
