The correct Answer is:
To determine which of the following is not a secondary sex organ, we need to categorize each option as either a primary or secondary sex organ. ### Step-by-Step Solution: 1. **Understand the Definitions**: - **Primary Sex Organs**: These are the main reproductive organs responsible for producing gametes. In males, the primary sex organs are the testes, and in females, they are the ovaries. - **Secondary Sex Organs**: These include structures that support the reproductive process but do not produce gametes. They can include glands and ducts that aid in reproduction. 2. **Analyze Each Option**: - **(1) Prostate Gland**: This is a gland in males that produces seminal fluid, which is part of semen. It is considered a secondary sex organ. - **(2) Mammary Gland**: This gland is involved in milk production in females and is also classified as a secondary sex organ. - **(3) Seminal Vesicle**: This is another gland in males that contributes to the production of seminal fluid. It is a secondary sex organ. - **(4) Ovary**: This is the primary sex organ in females, responsible for producing ova (eggs). 3. **Identify the Correct Answer**: - From the analysis, the ovary is the only option that is not a secondary sex organ; it is a primary sex organ. Therefore, the correct answer is **(4) Ovary**. ### Final Answer: The organ that is not a secondary sex organ is **(4) Ovary**.
