Solution
Recombinase enzymes, such as the protein RecA in bacteria and DMC1 and RAD51 in eukaryotes, play a crucial role in facilitating crossing over.
These enzymes help to catalyze the breakage and rejoining of DNA strands between homologous chromosomes.
They promote the exchange of DNA segments, resulting in the formation of new combinations of alleles on the chromosomes.
Therefore, the correct answer is option (B) Recombinase.
