What is the proper distance between fencers when they come on guard?

The proper distance between fencers when they come on guard requires the weapons' points to be in line with each other without overlapping. This positioning allows both fencers to maintain a safe distance while still being ready to engage in combat. If the points were to overlap, it could create an unsafe situation where one fencer might accidentally be hit without an official action occurring.

By having the weapons aligned and not overlapping, fencers can effectively maintain control over their actions and respect each other's space. It also sets a clear foundation for initiating actions and parries, ensuring that the bout proceeds fairly and safely.

The other options suggest distances or positions that don't conform to the standard practice and would not be considered safe or effective in a bout. For instance, suggesting that points must be 1 foot apart doesn't accurately reflect the dynamic nature of fencing, while a crouched position is not a requirement for being on guard. Therefore, the correct answer reflects the established guidelines for maintaining the appropriate distance in fencing.
