At the player's option, dew and frost can be classified as which of the following?

Dew and frost are classified as neither temporary water nor a loose impediment according to the Rules of Golf. Temporary water refers to any accumulation of water on the course that is temporary in nature, which could affect a player's ability to make a stroke. On the other hand, a loose impediment consists of natural objects that have not been tightly bound or adhered to the ground, such as leaves or twigs.

Dew and frost do not fit into these categories. They do not create a situation where a player would take relief as temporary water does, nor are they considered objects that can be moved as loose impediments. While players may encounter them during play, the classification does not apply, and they do not impact gameplay in the same way that the other two categories might.
