During a stipulated round, players must refrain from doing which of the following?

During a stipulated round, players are governed by the rules of golf, which include specific guidelines about conduct to ensure fair play and integrity. The correct answer encompasses several key prohibitions:

Giving advice is strictly limited to maintain the competitive nature of the game. Players can only receive advice from their caddies. By preventing players from giving advice to one another, the rules help avoid any potential advantages that could arise from shared strategies or insights during the competition.

Touching another player's equipment is also prohibited. This is to respect the ownership and personal space in the game. Every player's equipment is essential to their game strategy and touching someone else's equipment could inadvertently cause damage or interfere with their play.

Regarding asking for advice, players are limited to seeking input only from their caddies during a stipulated round. This restriction is in place to ensure that players are solely responsible for their own decisions and gameplay, reinforcing the principle of individual skill.

Embracing all these elements collectively underlines the importance of maintaining fairness, respect, and integrity during play, which is why "all of the above" is the correct answer. Each option reflects a vital aspect of etiquette and conduct that players must adhere to in a competition setting.
