Explanation:

The formula of Volume(V) vs Temperature(T) in Kelvin scale for an ideal gas at constant pressure and mass is #V/T # = constant=#c#

Or, #V=cT #

Now,compare this with #y=mx#

That means,this is an equation of straight line,passing through origin,so the correct choice is the last option.

So,here #c# is the slope of the curve i.e #tan theta = c#
