The correct Answer is:
To solve the question, we need to identify which type of characteristics are being described. 1. **Understanding the Question**: The question describes characteristics such as the development of pubic hair in both sexes, breasts in females, and facial hair like moustaches and beards in males. We need to determine whether these characteristics are primary sexual characteristics, secondary sexual characteristics, or both. 2. **Defining Primary Sexual Characteristics**: Primary sexual characteristics are those that are directly involved in reproduction. They are present at birth and are necessary for the reproductive process. Examples include the presence of reproductive organs. 3. **Defining Secondary Sexual Characteristics**: Secondary sexual characteristics, on the other hand, are features that develop during puberty and are not directly involved in reproduction. They include physical traits such as the development of breasts in females, facial hair in males, and pubic hair in both sexes. 4. **Analyzing the Given Characteristics**: The characteristics mentioned in the question (pubic hair, breasts, facial hair) are not directly involved in reproduction but are physical traits that appear during puberty. Therefore, they fit the definition of secondary sexual characteristics. 5. **Selecting the Correct Answer**: Since the characteristics described in the question are secondary sexual characteristics, the correct answer is (b) Secondary Sexual. Final Answer: (b) Secondary Sexual ---
