Your answer would be B, the formation of gametes.
Meiosis creates four daughter cells from one parent cell. The daughter cells all have one half of the chromosomes the parent cell does; 23.
These daughter cells can be gametes - cells that when reuniting with one from an opposite gender from reproduction, they form a zygote. When recombining, the 23 chromosomes join with the other 23 to form the original 46 chromosomes, giving the child genes from both parents and a full set of chromosomes.
Hope this helped!
