"The number of chromosomes present in a diploid cell doubles for each generation because there are two parent" is the one among the two statements that is the best explanation for why the chromosome numbers above are all even. The correct option among the two options that are given in the question is the second option or option "B". 

Answer;

B.) The number of chromosomes present in a diploid cell doubles for each generation because there are two parent.

Explanation;

-A diploid cell is a cell that contains two sets of chromosomes. This is double the haploid chromosome number. Each pair of chromosomes in a diploid cell is considered to be one homologous chromosome set.

-A single chromosome set consists of two chromosomes, one of which is donated from the mother and the other from the father. Humans have 23 sets of homologous chromosomes (which makes  46 chromosomes).
