B Correct answer
Explanation

Recombination of genes takes place at pachytene stage. During pachytene stage of meiosis I, non-sister adjacent chromatids in a tetrad, coil around each other at one or more points called Chiasmata. Chromatids break down at Chiasmata and then rejoin with the exchange of segments resulting in recombinants.
