D. incomplete wit egg and adult stages.

Answer

**Step-by-Step Solution:**

1. **Understanding Metamorphosis**: Metamorphosis is the process of transformation that an organism undergoes from its early developmental stages to its adult form. There are two main types of metamorphosis: complete and incomplete.

2. **Identifying the Types of Metamorphosis**:
- **Complete Metamorphosis**: This involves four distinct stages: egg, larva, pupa, and adult. The larval stage looks entirely different from the adult.
- **Incomplete Metamorphosis**: This involves three stages: egg, nymph, and adult. The nymph stage resembles the adult but is typically smaller and may lack certain adult features.

3. **Life Cycle of Cockroaches**: The life cycle of a cockroach includes the following stages:
- **Egg**: The initial stage where the cockroach begins its life.
- **Nymph**: After hatching from the egg, the cockroach enters the nymph stage, which resembles the adult cockroach but is smaller and lacks fully developed wings.
- **Adult**: The final stage where the cockroach reaches maturity and develops all adult characteristics.

4. **Analyzing the Nymph Stage**: In cockroaches, the nymph stage closely resembles the adult stage in appearance, indicating that the metamorphosis is incomplete. There are no drastic changes in form between the nymph and the adult.

5. **Conclusion**: Since the nymph of the cockroach looks very similar to the adult and there is no pupal stage, the type of metamorphosis exhibited by cockroaches is classified as **incomplete metamorphosis**.

**Final Answer**: The metamorphosis shown by cockroaches is **incomplete metamorphosis**.
