The correct answer is option B, that is, crossing over.  

Crossing over or chromosomal crossover refers to the interchange of genetic substance between the two homologous chromosomes non-sister chromatids, which leads to the formation of recombinant chromosomes at the time of sexual reproduction.  

It takes place in the pachytene stage of prophase I of meiosis at the time of a procedure known as synapsis.
