To solve this problem, we need to identify the correct sequence of events during mitosis. Let's analyze the stages of mitosis:$\newline \bullet$Condensation:$\newline$ - During prophase, the chromatin condenses into visible chromosomes.$\newline \bullet$Nuclear membrane disassembly:$\newline$ - The nuclear envelope breaks down, allowing spindle fibers to interact with chromosomes.$\newline \bullet$Arrangement at equator:$\newline$ - During metaphase, chromosomes align at the metaphase plate (equatorial plane).$\newline \bullet$Centromere division:$\newline$ - In anaphase, the centromeres divide, and sister chromatids are pulled apart.$\newline \bullet$Segregation:$\newline$ - The separated chromatids move to opposite poles of the cell.$\newline \bullet$Telophase:$\newline$ - Chromosomes de-condense, nuclear membranes reform, and the cell prepares to divide.$\newline$Now, let's match these stages with the given options:$\newline$Option 1: Condensation$\rightarrow$ Nuclear membrane disassembly$\rightarrow$ arrangement at equator$\rightarrow$ centromere division$\rightarrow$ Segregation$\rightarrow$ Telophase.$\newline$This sequence correctly follows the order of events in mitosis.$\newline$Therefore, the correct option is Option 1.
