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

• Refrigerants are chemical compounds used in cooling technologies, such as air conditioners.
• Air conditioners can use refrigerants to absorb heat and release cold air.
• The refrigerant dichloromethane is a hydrochlorocarbon (HCC).
• HCCs are composed of the elements hydrogen, chlorine, and carbon.
• The refrigerant tetradecafluorohexane is a perfluorocarbon (PFC).
• PFCs are composed of fluorine and carbon.

The student wants to contrast dichloromethane and tetradecafluorohexane. Which choice most effectively uses relevant information from the notes to accomplish this goal?

A

Dichloromethane, a hydrochlorocarbon, is composed of hydrogen, chlorine, and carbon; tetradecafluorohexane, a perfluorocarbon, is composed of fluorine and carbon.

B

Dichloromethane and tetradecafluorohexane are chemical compounds used in cooling technologies; the compounds are known as refrigerants.

C

The hydrochlorocarbon dichloromethane and the perfluorocarbon tetradecafluorohexane are both refrigerants that can be used in cooling technologies like air conditioners.

D

Tetradecafluorohexane, a refrigerant, can be used in cooling technologies to absorb heat and release cold air.
