Question

To ensure proper segregation of chromosomes during mitosis, the sister chromatid pairs must be stably bi-oriented on the mitotic spindle. In animal cells, after nuclear envelope break down (NEBD), chromosomes glide along the microtubules' length with the help oft he motor proteins. When the chromosomes reach the plus-end of microtubules, thekinetochores attach to the microtubules. Which one of the following is the correct option for the kinetochore-microtubules attachment configuration that ensures preprohormone some segregation?
