Solution

The correct option is A Crossing over between non-sister chromatids
Recombinases are genetic recombination enzymes.
These enzymes catalyse directionally sensitive DNA exchange reactions between short (30–40 nucleotides) target site sequences that are specific to each recombinase.
Recombinase in meiosis helps in crossing over between sister chromatids.
Thus, the correct answer is an option B.
