Answer

To identify the correct matches from the provided columns, we will analyze each item in Column I and match it with the appropriate items in Column II and Column III based on the information given.

### Step-by-Step Solution:

1. **Leishmania donovani**:
- This organism is known to cause **Kala-azar**, which is a disease transmitted by the **sand fly**.
- Match: **Leishmania donovani - b. Kala-azar - (iv) Sand fly**.

2. **Trichonympha**:
- Trichonympha is a type of protozoan that lives in the intestines of termites and is known for producing **glucosidases**.
- Match: **Trichonympha - c. Glucosidases - (i) Termites**.

3. **Nosema**:
- Nosema is a parasite that affects silkworms and is associated with a disease known as **Pebrine**.
- Match: **Nosema - d. Pebrine - (ii) Silk worm**.

4. **Trypanosoma**:
- Trypanosoma is known to cause **Sleeping sickness**, which is transmitted by the **tse-tse fly**.
- Match: **Trypanosoma - a. Sleeping sickness - (iii) Tse-tse fly**.

### Summary of Matches:
- 1) Leishmania donovani - b. Kala-azar - (iv) Sand fly
- 2) Trichonympha - c. Glucosidases - (i) Termites
- 3) Nosema - d. Pebrine - (ii) Silk worm
- 4) Trypanosoma - a. Sleeping sickness - (iii) Tse-tse fly

### Final Answer:
The correct matches are:
1) Leishmania donovani - b. Kala-azar - (iv) Sand fly
2) Trichonympha - c. Glucosidases - (i) Termites
3) Nosema - d. Pebrine - (ii) Silk worm
4) Trypanosoma - a. Sleeping sickness - (iii) Tse-tse fly

Thus, the correct option is the second one, which matches:
- 1st with B
- 2nd with C
- 3rd with D
- 4th with A
