a) The expected benefit of using child safety seats in automobiles is much higher than the expected benefit of using them on commercial passenger planes.
b) The marginal benefit of using child safety seats in automobiles equals the marginal cost of installing them, but the marginal benefit of using them on commercial passenger planes exceeds the marginal cost of installing them on planes.
c) The average benefit of using child safety seats in automobiles equals the average cost of installing them, but the average benefit of using them on commercial passenger planes exceeds the average cost of installing them on planes.
d) The expected benefit of using child safety seats in automobiles is much lower than the expected benefit of using them on commercial passenger planes.
