How does Le Chatelier's principle explain the effect of competitive inhibitors on enzyme reactions?

Competitive inhibitors increase the concentration of enzyme-substrate complex, causing the equilibrium to shift right.

Competitive inhibitors increase the concentration of free enzyme, causing the equilibrium to shift right.

Competitive inhibitors have no effect on the equilibrium of enzyme reactions.

Competitive inhibitors decrease the concentration of free enzyme, causing the equilibrium to shift left and decrease enzyme affinity for the substrate.
