In cockroach fertilization occurs in the

Options

A. oothecal chamber
B. genital chamber
C. oviducts
D. spermathecae

Answer

### Step-by-Step Solution:

1. **Understanding the Reproductive Systems**:
- The cockroach has distinct male and female reproductive systems. The male reproductive system includes paired testes, vas deferens, seminal vesicles, and an ejaculatory duct. The female reproductive system consists of paired ovaries, oviducts, spermatheca, and a genital chamber.

2. **Sperm Formation and Transfer**:
- In the male cockroach, sperm is formed in the testes and then transported through the vas deferens to the seminal vesicles, where they are packaged into bundles called spermatophores. During copulation, these spermatophores are released into the female's reproductive system.

3. **Egg Formation in Females**:
- In the female cockroach, eggs (ova) are produced in the ovaries and transported through the oviducts. The oviducts lead to the spermatheca, where sperm is stored after mating.

4. **Location of Fertilization**:
- Fertilization occurs in the genital chamber of the female cockroach. This is where the stored sperm from the spermatheca meets the ova, leading to fertilization.

5. **Identifying the Correct Answer**:
- The question asks where fertilization occurs in the cockroach. Based on the understanding that fertilization happens in the genital chamber, the correct answer is option B: **Genital Chamber**.
