The correct answer is B. Boxing.
The Queensbury rules are a set of rules governing boxing that were written by John Graham Chambers and adopted by the Marquess of Queensberry in 1867. The rules were designed to make boxing safer and more humane, and they have been used to govern professional boxing ever since.
The rules include a number of important provisions, such as the use of gloves, a three-minute round structure, and a ban on hitting below the belt. The rules also established the concept of a knockout, which is when a boxer is unable to continue fighting after being hit.
The Queensbury rules have had a profound impact on the sport of boxing. They have helped to make boxing a safer and more popular sport, and they have also helped to establish boxing as a legitimate professional sport.
The other options are incorrect because they are not sports that are directly influenced by the Queensbury rules.

Polo is a team sport played on horseback in which the objective is to score goals against an opposing team by driving a small white plastic or wooden ball into the opposing team’s goal using a long-handled mallet.
