Answer:
KE = 1/2 M V^2 = 1/2 * 25 * 10^2 = 1250 J

M2 = 1/2 M1
V2 = V1 / 2
E2 = 1/2 * 1/4 E1 = E1 / 8 = 10000 / 8 = 1250 J

An object that no force is applied to continues moving in the same direction, so if the doll was moving somewhere, it would keep doing so, except all of this makes no sense the doll is not in gravityless vacuum what are we even talking about.
The answer A is the least ridiculous.
