C. segmented body
D. 13 - chambered heart

Answer

To determine which of the following is a character of a cockroach, we will analyze each option provided:

1. **Reduced Wing**: Cockroaches have wings, but they are not considered reduced. They possess well-developed wings that allow them to fly, although some species may have varying degrees of wing development.

2. **Cocoon Formation**: Cockroaches do not form cocoons. Instead, they lay eggs in a protective case called an ootheca. This is a significant distinction from organisms that undergo complete metamorphosis and form cocoons.

3. **Segmented Body**: Cockroaches do have a segmented body, which is characteristic of arthropods. Their body is divided into three main parts: the head, thorax, and abdomen.

4. **13 Chambered Heart**: The heart of a cockroach is indeed 13-chambered. It is a tubular structure located in the dorsal part of the body, extending from the thorax to the abdomen, and it has 13 funnel-shaped chambers.

Based on the analysis of each option, the correct answer is:

**The character of a cockroach is the 13 chambered heart.**
