Under what condition can a player's caddie lift and mark the ball on the putting green?

A caddie can lift and mark the ball on the putting green when they have the player's authorization. This is an essential rule in the game of golf, which emphasizes the need for clear communication and consensus between the player and their caddie. The player's authorization ensures that the caddie is acting on the player's behalf and maintains the integrity of the game.

Caddies are expected to operate under the player's direction, especially in situations concerning the ball's position and the rules governing its movement. Authorizing a caddie to lift and mark the ball is generally done to facilitate play, such as when the player's line of putt is obstructed or when there is a need to clean the ball.

The other options do not accurately reflect the protocols or rules that govern play on the putting green.
