Escherichia coli has 4.6 × 10${}^9$ base pairs in its genome which are arranged in 4,000 genes; Drosophila melanogaster has 122,653,977 base pairs in its genome which are arranged in 17,000 genes. Human has 3.3 x 10${}^9$ base pairs in its genome which are arranged in 21,000 genes. Mycoplasma has 475 genes in its 0.58 Mbp genome. Oryza sativa has 3.7 x 10${}^8$ base pairs in its genome which are arranged in 55,000 genes. The correct answer is B.
