The correct Answer is:
To determine which statement is not correct about secondary sexual characters of females, we will analyze each option provided in the question. 1. **Option (a): Development of mammary gland** - The development of mammary glands is indeed a secondary sexual characteristic that occurs during puberty in females. It is associated with the enlargement of breasts, which is a clear indicator of sexual maturation. Therefore, this statement is correct. 2. **Option (b): Presence of pubic hair** - The presence of pubic hair is another secondary sexual characteristic that develops during puberty. It signifies the onset of sexual maturity in females. Thus, this statement is also correct. 3. **Option (c): Low pitched voice** - This statement is incorrect. In females, secondary sexual characteristics typically include a higher-pitched voice, not a low-pitched voice. The voice pitch in females usually becomes higher during puberty due to hormonal changes. Therefore, this option is the one that is not correct about secondary sexual characters of females. 4. **Option (d): Menarche** - Menarche refers to the first occurrence of menstruation, which is a significant event in female puberty and is considered a secondary sexual characteristic. This statement is correct. Based on the analysis, the option that is not correct about secondary sexual characters of females is: **Answer: (c) Low pitched voice** ---
