Answer 2

The statements A, B, C, and E are considered as are true for human chromosomes.

Explanation:

The statement D and F are not considered as true for human chromosome because, the statement D states that in the DNA double helix, the base adenine is always paired with guanine which is incorrect, because adenine always pairs with thymine through double hydrogen bond.

The statement F is considered as incorrect because, when a cell is not dividing, the chromosomes are not visible.
