Answer 1

The correct option is D

1 and 2 are correct.

Crossing over or recombination occurs during the pachytene stage of prophase I of meiosis. During metaphase II, sister chromatids migrate to opposite poles forming a single metaphase plate. In metaphase I, homologous pairs of chromosomes are spread across the metaphase plate. Progressive condensation and coiling of chromosome fibres occur during the leptotene stage of prophase I of meiosis.
