On a map with scale 1 : 250 000, the distance between cities A and B is 13 cm. On another map, with scale 1 : 300 000, the distance between cities A and C is 10 cm. On a third map, with scale 1 : 500 000, the distance between cities A and D is 9 cm. The actual distances between city A and cities B, C, and D are, respectively, equal to $X$, $Y$, and $Z$ (in the same unit of length).
The distances $X$, $Y$, and $Z$, in increasing order, are given in
(A) $X, Y, Z$.
(B) $Y, X, Z$.
(C) $Y, Z, X$.
(D) $Z, X, Y$.
(E) $Z, Y, X$.
