please provide the correct answer mentioning the correct option thanks

The question refer to the following reaction: In the manufacture of an important organic solvent, toluene (C7H8), from methyl cyclohexane (C7H14), the following reaction occurs: CH74(g)=C7H8(g)+3H2(g) Q1) The volume of the system is decreased at a constant temperature. A new equilibrium is established by a shift of the original equilibrium to the: A) Left and [C7H14(g)] increases B) Right and [C7H8 (g)] increases C) Left and [C7H14(g)] remains unchanged D) Right and [C7H8 (g)] remains unchanged
