Solution

The correct option is B Recombinase
Crossing over is the exchange of segments between the non-sister chromatids of homologous chromosome.
Recombinase is an enzyme that catalyzes the exchange of short pieces of DNA between two long DNA strands. It particularly catalyzes the exchange of homologous regions between the paired maternal and paternal chromosomes.
So, the correct option is 'Recombinase'.
