While researching a topic, a student has taken the following notes:

• Chromosomes are cellular structures that contain genes.
• Genes carry critical instructions for determining an organism’s physical traits.
• Members of the same species typically have the same number of chromosomes.
• As a species, the Tibetan antelope (Pantholops hodgsoni) has sixty chromosomes.
• As a species, the Sterkiella histriomuscorum, a simple, single-celled protozoan, has over 15,000 chromosomes.

The student wants to emphasize a difference between Pantholops hodgsoni and Sterkiella histriomuscorum. Which choice most effectively uses relevant information from the notes to accomplish this goal?

A

Sterkiella histriomuscorum, a simple, single-celled protozoan, has over 15,000 cellular structures called chromosomes.

B

Sterkiella histriomuscorum has over 15,000 chromosomes, which is far more than the sixty chromosomes Pantholops hodgsoni has.

C

Individual members of the Tibetan antelope species typically have the same number of chromosomes: sixty.

D

Sterkiella histriomuscorum and Pantholops hodgsoni both have chromosomes, which are cellular structures that contain genes.
