The value of the equilibrium constant (Kc) is less than 1 (0.143), indicating that the forward reaction (C₆H₁₂ → MCP) is not favored and the reverse reaction (MCP → C₆H₁₂) is favored. As the initial concentration of MCP (0.300 M) is greater than the equilibrium concentration (which is unknown), the system will have to shift in the reverse direction to consume some of the excess product, MCP, and reach equilibrium. Therefore, the system will shift left towards the reactants, which is the reverse direction. Hence, the answer is A.
