The correct Answer is:
To solve the question, we need to evaluate each statement provided in the question regarding the stages of cell division, specifically mitosis. ### Step 1: Analyze the first statement **Statement:** "Spindle fibres get attached to the kinetochore of the chromosomes during metaphase." **Evaluation:** This statement is **true**. During metaphase, the spindle fibers attach to the kinetochores located at the centromeres of the chromosomes, aligning them at the metaphase plate. ### Step 2: Analyze the second statement **Statement:** "At the end of prophase, cells do not show Golgi complex, endoplasmic reticulum, nucleolus, and the nuclear envelope." **Evaluation:** This statement is also **true**. At the end of prophase, the nuclear envelope breaks down, and the Golgi complex and endoplasmic reticulum are disassembled, making them not visible. ### Step 3: Analyze the third statement **Statement:** "At anaphase, centromere splits but chromatids do not separate." **Evaluation:** This statement is **false**. During anaphase, the centromere does split, and the sister chromatids separate and move toward opposite poles of the cell. ### Conclusion Based on the evaluations: - The first statement is true. - The second statement is true. - The third statement is false. Thus, the correct options are the first and second statements. ### Final Answer The correct options are **A and B**. ---
