dear student
the correct answer is2
According to Le Chateliar’s principle, removing ammonia from the reaction would drive the reaction in the forward direction.
Since the reaction is exothermic, according to Le chateliar principle, by increasing the temperature of the system, the reaction will go in the backward direction.

Dear student
 
if we increase amount of N2 and H2 , then also ot would result in forward Direction.
 
hence I think option 2 amd 4 should be correct

a principle stating that if a constraint (such as a change in pressure, temperature, or concentration of a reactant) is applied to a system in equilibrium, the equilibrium will shift so as to tend to counteract the effect of the constraint.so according to this principle  reaction will go in bacjward direction!!
