Solution

The correct option is D homologous chromosomes; sister chromatids
The kinetochore is a proteinaceous disc-shaped structure near the centromere which helps in cell division.

Metaphase I of meiosis I: The homologous chromosomes align at the equatorial plate. The spindle microtubules attach to the kinetochore of the homologous chromosomes.

Metaphase II of meiosis II: The chromosomes align at the equatorial plate and the spindle microtubules attach to the kinetochores of the sister chromatids.
