A ball is slightly too large to fit through a hole in a flat plate. The drawing shows two arrangements A A B of this situation. In Arrangement I the ball is made from metal A Arrangement I Arrangement I and the plate from metal B. When both the ball and the plate are cooled by the same number of Celsius degrees, the ball passes through the hole. In Arrangement II the ball is also made from metal A, but the plate is made from metal C. Here the ball passes through the hole when both the ball and the plate are heated by the same number of Celsius degrees. Rank the coefficients of linear thermal expansion of metals A, B, and C in descending order (largest first):
(a) aB, aA, ac
(b) a, ac, aA
(c) ac, a, aA
(d) ac, aA, ag
(e) aA, aB, ac
