Solution
The correct option is C Initially H2 combines with O2, therefore rapid fall in pressure will be observed. then gradually adsorption of CO will occur by activated charcoal.
As the adsorption increases, the pressure decreases.
With time pores of charcoal decrease.
So initial it will decrease fast but after some time its decrease rate will be slow.
Option (b) is correct
