The equilibrium constant for a reaction is given by the product of the concentrations (or partial pressures) of the products raised to their stoichiometric coefficient divided by the product of the concentrations (or partial pressures) of the reactants raised to their stoichiometric coefficient. 
For the given reaction, 
K = ([C]^c)/([A]^2[S]^2[B]^b) 
Substituting the values, we get 
K' = ([C]^c)/(([A]^2[S]^2[B]^b)^2) 
= K^2 
= 100 (since K=10) 
Hence, the answer is D.
