Hi Matilda


I`d choose {B} as the only correct answer to the context.
[A] is possible only if we make some changes:
"Green contained in the chromosomes are thought of us as the units of heredity."

Hi Matilda
.
Your sentence would make a whole lot more sense with two changes:
Genes are contained in the chromosomes, and they are thought of as the units of heredity.
.
Answer B works quite nicely then.
