At some constant equilibrium temperature T K, the following gaseous equilibrium is set in a vessel fitted with a movable piston. \[{{N}_{2}}+3{{H}_{2}}\overset{{}}{leftrightarrows}2N{{H}_{3}}\] Now at this equilibrium state, total pressure is increased to some extent so as to attain a new equilibrium state. Which of the following will be true at the new equilibrium state?

A)  concentration of \[N{{H}_{3}}\] will increase but that of \[{{N}_{2}}\] and \[{{H}_{2}}\] will remain same,

B)  concentration of \[N{{H}_{3}},\,{{N}_{2}}\] and \[{{H}_{2}}\] will increase

C)  There shall be no change in the concentration of any of these gases

D)  concentration of \[N{{H}_{3}}\] will increase but that of \[{{N}_{2}}\] and \[{{H}_{2}}\] will decrease
