Options

A. Natural immunity
B. Acquired immunity
C. Innate immunity
D. Passive immunity

Answer

To solve the question "The immunity associated with memory is called," we can follow these steps:

### Step 1: Understand the Types of Immunity
First, we need to identify the different types of immunity that exist. The main types are:
- **Innate Immunity**: This is the natural defense system we are born with, which does not have memory.
- **Acquired Immunity**: This immunity develops after exposure to a pathogen and is associated with memory.
- **Passive Immunity**: This is immunity gained through the transfer of antibodies from another source, such as maternal antibodies.
- **Natural Immunity**: This is a type of acquired immunity that occurs when a person is exposed to a pathogen naturally.

### Step 2: Identify the Key Concept of Memory in Immunity
The question specifically asks about immunity that is associated with memory. This is a crucial point because:
- Memory cells are responsible for the long-lasting immunity that develops after the first encounter with a pathogen.

### Step 3: Analyze the Options
Now, we can analyze the options based on our understanding:
- **Innate Immunity**: Incorrect, as it does not involve memory.
- **Acquired Immunity**: Correct, as it involves memory cells that remember past infections.
- **Passive Immunity**: Incorrect, as it does not involve the body’s own memory but rather the transfer of antibodies.
- **Natural Immunity**: While it involves a primary response, it is not specifically termed as memory-associated immunity.

### Step 4: Conclusion
Based on the analysis, the immunity associated with memory is called **Acquired Immunity**.

### Final Answer
**Acquired Immunity**
