Mark the incorrect statement

Options

A. Labia majora is homologous to scrotal sacs of males
B. Clitoris is homologous to penis in males
C. Labia minora is homologous to scrotal sacs in males
D. Prostate gland secretion contains the enzyme fibrinolysin ( plasmin)

Answer

**Step-by-Step Solution:**

1. **Identify the Statements**: The question asks us to mark the incorrect statement among four given statements related to human reproductive anatomy.

2. **Analyze Each Statement**:
- **Statement 1**: "Labia majora is homologous to scrotal sac of males."
- **Analysis**: The labia majora (female) and scrotal sac (male) are both external reproductive structures. This statement is correct.

- **Statement 2**: "Clitoris is homologous to penis in male."
- **Analysis**: The clitoris (female) and penis (male) are both sensitive organs involved in sexual arousal and are homologous structures. This statement is also correct.

- **Statement 3**: "Labia minora is homologous to scrotal sac in male."
- **Analysis**: The labia minora (female) is an internal structure, while the scrotal sac (male) is an external structure. Since they are not comparable in terms of being homologous, this statement is incorrect.

- **Statement 4**: "Prostate gland secretion contains enzyme fibrinolysine."
- **Analysis**: Fibrinolysine is indeed present in prostate secretions and helps maintain the sterility of semen. This statement is correct.

3. **Conclusion**: Based on the analysis, the incorrect statement is the third one: "Labia minora is homologous to scrotal sac in male."

**Final Answer**: The incorrect statement is: "Labia minora is homologous to scrotal sac in male."
