Picking up marbles and placing them in a sack

Explanation:

The entropy of a chemical system is defined as the measure of disorder. Therefore a negative change in entropy is the movement to a more ordered state. The only option here which achieves a more ordered state, would be the first option.

Picking up marbles and placing them in a stack achieves more order, rather than the other options - that achieve more disorder.

i'm pretty sure its b i might be wrong though!
