Option (b) is correct.
 
Given:
 
n = 10 mol
 
V = 8.21 L
 
We have,
 
PV = nRT
 
straight P over straight T equals nR over straight V= constant
 
Intercept on y aixs = 
 
equals log nR over straight V equals log fraction numerator 10 cross times 0.0821 over denominator 8.1 end fraction equals space log space 0.1 equals space 0.9941 almost equal to 0.1
 
As nR over straight V is always constant, the graph of P/T Vs T is a straight line parallel to temperature axis and slope is zero.
