C. The circulatory system provides oxygen that the respiratory system uses to fill the lungs

has properties similar to other elements in group 18

does not react readily with other elements

is part of the noble gas group

Explanation:

Argon (Ar) is in group 18. All elements in group 18 of the periodic table are called inert or noble gases. All group 18 elements have 8 valence electrons or octet (complete shell), hence these elements are chemically inert or they neither lose or gain electrons from other elements. Inert gases do not react readily with other elements. All inert gases of group 18 are similar to each other.
