ANS:B - greater dimensional stability of the casting.

Uniform ramming of sand in green sand molding process leads to greater dimensional stability of the casting. Uniform ramming of sand ensures consistent density and compaction throughout the mold, which helps in maintaining the shape and dimensions of the casting during the pouring and solidification process. Inconsistent compaction can lead to variations in mold density, resulting in dimensional inaccuracies and defects in the final casting. Therefore, uniform ramming is essential for achieving precise and consistent casting dimensions.
