Why Should Molten Wax Application onto Dies Be Accomplished Slowly

Why should molten wax application onto dies be accomplished slowly and in thin layers when creating a casting pattern?

A) Careful use minimizes porosity
B) This promotes wetting of the wax on the dies
C) This avoids distortion from thermal contraction during wax cooling
D) This has a tendency to sag because of low modulus
E) This has susceptibility to water absorption
