You Are Filling a Jar of Honey from the Spigot

You are filling a jar of honey from the spigot at the bottom of a large barrel at the grocery store. The honey flows extremely slowly, so the store manager has the barrel refilled. Now the honey flows much more rapidly from the spigot because

A) the pressure of the honey at the bottom of the barrel increases as the height of honey in the barrel increases.
B) the density of the honey decreases as the height of the honey in the barrel increases.
C) the viscosity of the honey decreases as the height of honey in the barrel increases.
D) the viscosity of the honey increases as the height of honey in the barrel increases.
