The correct answer is: The figure shows Langmuir adsorption isotherm
This is Freundlich isotherm not Langmuir.

It is also written as

logxm=logk+1nlogp

where

x = mass of adsorbate

m = mass of adsorbent

p = Equilibrium pressure of adsorbate

K and n are constants for a given adsorbate and adsorbent at a particular temperature.
