What is the relationship between the number of chromosomes in anorganism's genome and its biological complexity?

a) more complex organisms have a higher number of chromosomesdue to a higher number of genes

b) organisms have the same number of chromosomes, even thoughthey vary in complexity

c) there is no relationship, many less complex organisms have alarge number of chromosomes

d) less complex organisms have fewer chromosomes because ittakes less time and energy to replicate their cells

e) less complex organisms tend to have more chromosomes and moreproteins encoded by them
