Question

Which of the following are the properties of acquired immunity?

• A. Specificity

Answer 1

The correct option is D All of the above

A. Specificity- It is the ability to differentiate between various foreign molecules.

B. Diversity- It can recognize a vast variety of foreign molecules,

C. Immunological memory- When the immune system encounters a specific foreign agent for the first time, it generates an immune response and eliminates the invader. This is called the first encounter. The immune system retains the memory of the first encounter. As a result, a second encounter occurs more quickly and abundantly than the first encounter.

So, the correct answer is "All the above".
