C. a-t,b-s,c-q,d-p
D. a-t,b-q,c-p,d-s

Answer

To solve the matching question between Column I and Column II, we will analyze each item in Column I and find its corresponding item in Column II based on the diseases and their causative agents.

### Step-by-Step Solution:

1. **Identify the first item in Column I: Pneumonia**
- Pneumonia is a severe lung infection caused by bacteria.
- The specific bacterium responsible for pneumonia is **Diplococcus pneumoniae**.
- Therefore, the match is: **(a) Pneumonia - (t) Diplococcus pneumoniae**.

2. **Identify the second item in Column I: Citrus Canker**
- Citrus canker is a plant disease that affects citrus fruits.
- It is caused by the bacterium **Xanthomonas citri**.
- Therefore, the match is: **(b) Citrus Canker - (s) Xanthomonas citri**.

3. **Identify the third item in Column I: Cholera**
- Cholera is a highly infectious disease characterized by severe diarrhea and dehydration.
- It is caused by the bacterium **Vibrio cholerae**.
- Therefore, the match is: **(c) Cholera - (p) Vibrio cholerae**.

4. **Identify the fourth item in Column I: Leprosy**
- Leprosy is a chronic infectious disease that causes skin lesions and nerve damage.
- It is caused by the bacterium **Mycobacterium leprae**.
- Therefore, the match is: **(d) Leprosy - (q) Mycobacterium leprae**.

### Final Matches:
- (a) Pneumonia - (t) Diplococcus pneumoniae
- (b) Citrus Canker - (s) Xanthomonas citri
- (c) Cholera - (p) Vibrio cholerae
- (d) Leprosy - (q) Mycobacterium leprae

### Summary of Correct Combinations:
- A - T
