The correct Answer is:
To determine the correct answer to the question regarding the changes that occur in females at the onset of puberty, let's analyze each option step by step. ### Step 1: Understand the Changes at Puberty Puberty is a developmental stage characterized by the onset of secondary sexual characteristics, which are influenced by hormones, primarily estrogen in females. ### Step 2: Analyze Each Option - **Option (a): The enlargement of breasts** - This is a well-known change that occurs during puberty due to hormonal influences. The breasts develop as a secondary sexual characteristic. - **Option (b): Beginning of menstrual cycle** - The onset of menstruation (menarche) is a significant event in female puberty, marking the beginning of reproductive capability. - **Option (c): Stoppage of growth of long bone and height** - During puberty, the growth plates in long bones close, which leads to the cessation of height increase. This is a crucial change as it marks the end of vertical growth. ### Step 3: Conclusion Since all three options (a, b, and c) describe changes that occur in females at the onset of puberty, the correct answer is: **(d) All the above** ### Final Answer The correct option is **(d) All the above**. ---
