Final answer:
The player must identify the ball to take relief under the unplayable ball Rule (19.2). If the ball is not identifiable, it is treated as a lost ball, and the player takes stroke-and-distance relief. Also, carrying a metal club in an open fairway during a lightning storm makes a golfer vulnerable, and being under a tree is risky as well.
Step-by-step explanation:
When dealing with a situation where a player's ball is lost or out of bounds, such as coming to rest in a tree, Rule 19.2 of the Rules of Golf becomes relevant. Specifically:
- The player must identify the ball before taking relief under the unplayable ball Rule (19.2), hence option 1 is correct.
- If a ball is not identifiable as their own, the player may not proceed with the unplayable ball relief options 2 and 3. Instead, they must treat it as a lost ball and take stroke-and-distance relief by playing another ball from where the last stroke was made (see Rule 18.2).
Moreover, addressing the safety concern, a golfer with a metal club over her shoulder is particularly vulnerable to lightning in an open fairway because they could act as a lightning rod, increasing the risk of being struck by lightning. Taking shelter under a tree during a thunderstorm is also unsafe, as the tree can attract lightning, posing a significant risk of harm. The safest option during such situations is to evacuate to a secure indoor area.
