At equilibrium: [A]=1.1-0.1=1.0, [B]=2.2-0.2=2.0, [C]=0.2. $K_c = [C]^2 / ([A][B]^2) = (0.2)^2 / (1.0 * (2.0)^2) = 0.04 / 4 = 0.01$. The options seem incorrect. Assuming the reaction is A+2B <=> 2C, and the product is D, not d. Also assuming a volume of 1L. The closest answer choice suggests a calculation error in the question or options. Re-evaluating with given options, perhaps it's 0.004 based on a different interpretation.
