B. Pila globosa - pearl
C. Apis indica - Honey
D. kenis lacca - Lac

Answer

To solve the question "Which one of the following pairs is mismatched?", we will analyze each option provided:

1. **Bombix mori** - This is the scientific name for the silkworm, which is known for producing silk. This pair is correctly matched.

2. **Pylaglobosa** - This name is associated with a type of mollusk, but it is incorrectly matched with pearl production. Pearls are produced by pearl oysters, specifically the species **Pinctada maxima**. Therefore, this pair is mismatched.

3. **Apis indica** - This is the scientific name for the Indian honeybee, which is known for producing honey. This pair is correctly matched.

4. **Canis lacca** - This refers to the lac insect, which produces lac. This pair is also correctly matched.

From the analysis, the mismatched pair is **Pylaglobosa that produces pearl**.

### Step-by-Step Solution:
1. **Identify the options**: Read through the provided pairs to identify what each organism is known for.
2. **Analyze each pair**:
- Confirm the accuracy of the first pair (Bombix mori - silk).
- Check the second pair (Pylaglobosa - pearl) and identify the correct organism that produces pearls.
- Verify the third pair (Apis indica - honey).
- Confirm the fourth pair (Canis lacca - lac).
3. **Determine the mismatched pair**: After analyzing all pairs, identify which one does not correctly match the organism with its product.
4. **Conclude the answer**: State that the mismatched pair is **Pylaglobosa that produces pearl**.
