Mark the odd one (w.r.t. NPV)

Options

A. Narrow spectrum herbicide
B. Species specific
C. Bioinsecticide
D. Nucleoprotein particles

Answer

To solve the question of marking the odd one out with respect to NPV (Nuclear Polyhedrosis Virus), we will analyze each option provided.

### Step-by-Step Solution:

1. **Understand NPV**:
- NPV stands for Nuclear Polyhedrosis Virus, which is a virus belonging to the family Baculoviridae.
- It acts as a biopesticide, primarily targeting pests like moths and butterflies.

2. **Analyze the Options**:
- **Option A: Narrow Spectrum Herbicides**:
- Herbicides are chemicals used to kill unwanted plants (weeds).
- NPV is a biopesticide, not a herbicide. Therefore, this option is not related to NPV.

- **Option B: Species Specific Bioinsecticides**:
- Bioinsecticides are derived from natural materials and are specific to certain pests.
- NPV is indeed species-specific as it targets specific insects like moths and butterflies. This option is related to NPV.

- **Option C: Nucleoprotein Particles**:
- NPV consists of nucleoprotein particles, which include genetic material (DNA or RNA) and protein coats.
- This option accurately describes a characteristic of NPV and is therefore related.

3. **Identify the Odd One Out**:
- From the analysis, Option A (Narrow Spectrum Herbicides) is the only option that does not relate to NPV, as NPV is a biopesticide and not a herbicide.

### Conclusion:
- The odd one out with respect to NPV is **Option A: Narrow Spectrum Herbicides**.
