Answer #2

According to Le Chatelier's principle,

If a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium moves to counteract the change

Triple the temperature woukd shift the equilibrium to the left. The reaction shown is exothermic. So when temperature os increased accroding to the principle conditions to counteract the change will occur and hence equilibrium shifts towards the left.

In all the other options, the concentrations are increased on the LHS and hence equilibirum shifts to the right to counteract it
