by your standards fail means not state rank lol.
nah seriously chemistry is by far my worst. I won't fail as in less than 50% but it'll probably be the units that don't count

explain to me please someone :)
There are more Gaseous molecules on the right, therefore increased pressure would drive it to the left. B is wrong.

The reaction is Exothermic, so an increase in temperature would drive the reaction to the left. C is wrong.

A Catalyst is used to speed up rate of reaction, but does not shift the equilibrium. (I think? Might be wrong on its purpose, but it certainly doesnt shift equilibrium). So A is wrong.

More of the reactant would increase the concentration of reactants on the left hand side, so to counter the change by Le Chatlier the reaction will be driven to the right. Therefore, the answer is D
