In which situation can a referee not decide a team disqualification?

The correct choice highlights that a referee must adhere to specific rules when determining if a team should be disqualified. Rule 5.6.5 typically outlines particular criteria or conditions under which disqualification can occur. Without referencing these regulations, a referee lacks the authority to impose such a severe penalty as team disqualification.

This specificity ensures that decisions are consistent, fair, and uphold the integrity of the sport. The other situations presented do not reflect the procedural standards or contextual limitations regarding a referee's authority. Factors like the nature of youth sports or the timing of the game do not inherently determine the referee's ability to enforce disqualification without the grounding rules cited in the regulations.
