A restaurant uses, to serve beverages, trays with square bases. All glasses in this restaurant have the format represented in the figure.
Consider that $\overline{AC} = \frac{7}{5}\overline{BD}$ and that $l$ is the measure of one of the sides of the base of the tray.
What should be the smallest value of the ratio $\frac{l}{d}$ for a tray to have the capacity to carry exactly four glasses at once?
(A) 2
(B) $\frac{14}{5}$
(C) 4
(D) $\frac{24}{5}$
(E) $\frac{28}{5}$
