Step-by-step explanation:
In match play, if a player's approach shot comes to rest on an elevated putting green and they mistakenly play a different ball, the ruling is that they have played a wrong ball and the error must be corrected. This means that the player must disregard the ball they just put in and continue playing with their original ball. The player will receive a penalty of two strokes for playing the wrong ball, as per the rules of golf.
Option 1 is the correct answer. The player's action constitutes playing the wrong ball, and according to the Rules of Golf, the player needs to rectify the mistake by continuing to play with the original ball. There may be penalties associated with playing the wrong ball, depending on the circumstances, but the primary focus is on correcting the error and maintaining the integrity of the game.
