The marginal revenue function is the derivative of the demand function with respect to quantity, multiplied by the price. Thus, MR = (dQ/dp)*p + Q = (1/100)*p + Q. Simplifying this expression using the given demand function Q = 1400 - 100p, we get MR = 14Q - Q^2/100. This matches option (B), which is 14*(F1F1F1S1 - F1F1F10)*Q/50.
