Choose the incorrectly matched pair

Options

A. B cells - Humoral immunity
B. Cytokines - interferons
C. Passive immunity - Long lasting
D. Antibodies - immunoglobulins

Explanation

To solve the question "Choose the incorrectly matched pair," we will analyze each option provided in the context of human health and disease, specifically focusing on immunity.

### Step-by-Step Solution:

1. **Understand the Terms**:
- **B cells**: These are a type of white blood cell that plays a significant role in the immune response by producing antibodies.
- **Humeral Immunity**: This refers to the aspect of immunity that is mediated by antibodies produced by B cells, which circulate in body fluids (humeral).

**Hint**: Remember that B cells are primarily responsible for producing antibodies in the humoral immune response.

2. **Evaluate the First Pair**:
- B cells and humeral immunity are correctly matched because B cells are indeed responsible for humoral immunity.

**Hint**: Check if the function of B cells aligns with the type of immunity mentioned.

3. **Examine the Second Pair**:
- **Cytokines**: These are signaling proteins that mediate and regulate immunity, inflammation, and hematopoiesis.
- **Interferons**: A type of cytokine that is particularly important in the immune response against viruses.

**Hint**: Understand that interferons are a subset of cytokines, which makes this pair correctly matched.

4. **Analyze the Third Pair**:
- **Passive Immunity**: This is immunity acquired by the transfer of antibodies from one individual to another, such as from mother to child.
- The statement claims that passive immunity is long-lasting.

**Hint**: Consider the duration of passive immunity and whether it is typically short or long-lasting.

5. **Determine the Correctness of the Third Pair**:
- Passive immunity is indeed short-lasting because the antibodies transferred do not remain in the recipient's body for a long time. Therefore, matching passive immunity with "long-lasting" is incorrect.

**Hint**: Recall that passive immunity does not involve the recipient's immune system creating its own antibodies, which contributes to its short duration.

6. **Review the Fourth Pair**:
- **Antibodies and Immunoglobulins**: Antibodies are also known as immunoglobulins, which are proteins produced by B cells to identify and neutralize pathogens.

**Hint**: Recognize that antibodies and immunoglobulins are synonymous terms.

7. **Conclusion**:
- After evaluating all pairs, the incorrectly matched pair is "Passive Immunity - Long Lasting." The correct match should be "Passive Immunity - Short Lasting."

### Final Answer:
The incorrectly matched pair is **Passive Immunity - Long Lasting**.
