Effect of nature of gas on pressure ratio - Thermodynamics

Q.  A gas being the best behaved thermodynamics substance, what is the relation between the ratio of pressure (p) of a gas at any temperature to pressure (pt) of same gas at triple point temperature and the nature of gas?

a. the ratio (p/pt) approaches a constant value which is dependent of nature of gas
b. the ratio (p/pt) approaches a constant value which is independent of nature of gas
c. the ratio (p/pt) approaches a various values which are dependent of nature of gas
d. none of the above

ANSWER: the ratio (p/pt) approaches a constant value which is independent of nature of gas
