An Expectation That Has Been Borne Out by Comparative Genomic

An expectation that has been borne out by comparative genomic analysis is that:

A) Increased degrees of complexity in multicellular organisms are closely correlated with increased genome sizes.
B) Increased genome size correlates with an increased number of genes.
C) All vertebrate genomes are roughly the same size.
D) Human and chimpanzee sequences are closely related.
