When a Mixture Is Prepared from 15

When a mixture is prepared from 15.0 L of ammonia and 15.0 L of chlorine measured at the same conditions, these compounds react according to the following equation:
2NH₃(g) + 3Cl₂(g) → N₂(g) + 6HCl(g)
When the reaction is completed, what are the volumes of the gases (NH₃, Cl₂, N₂, and HCl, respectively) ? Assume the final volumes are measured under identical conditions.

A) 0.00 L, 0.00 L, 5.00 L, and 30.0 L
B) 0.00 L, 0.00 L, 7.50 L, and 45.0 L
C) 0.00 L, 5.00 L, 7.50 L, and 45.0 L
D) 5.00 L, 0.00 L, 5.00 L, and 30.0 L
E) 0.00 L, 10.0 L, 15.0 L, and 90.0 L
