What should a player do if their ball is accidentally moved by someone else?

When a player's ball is accidentally moved by someone else, the correct action is to replace it to its original spot. The rules of golf state that if a ball at rest is moved by an outside influence, such as another player, the ball must be put back in its original location. This rule ensures fairness and maintains the integrity of the game, allowing play to continue without penalty for the player whose ball was moved.

The other options do not align with the established rules. Playing from wherever the ball lies would not rectify the situation, and calling for a ruling is unnecessary since the rules clearly outline what should be done. Lifting and checking the ball is inappropriate in this scenario as it does not apply to the situation of an outside influence moving the ball. Replacing the ball ensures that the game proceeds according to the regulations set forth by the governing bodies of golf.
