For first question correct option is B.
As q is greater than equilibrium constant os reaction will takes place in backward directions.
For next questions correct that option is coming
Increase in pressure means no. Of moles per unit volume increase so according to Let Chatilier principle equilibrium shift in the direction in which there is decrease in no. Of moles. So equilibrium shift to left side.
