Which of the following is NOT a men's bodyweight category for Sub-junior and junior lifters?

The correct option, indicating a bodyweight category that does not exist for Sub-junior and junior lifters, is indeed the 78 kg category. In powerlifting, the bodyweight categories for Sub-junior and junior men's lifters are established based on national and international federation standards.

Common weight classes for men's Sub-junior and junior categories include thresholds such as 53 kg, 66 kg, and 105 kg, which all align with the typical categorization recognized in competitive settings. The absence of the 78 kg category reflects the classification systems in place, where those categories have either been adjusted or omitted for this particular group of lifters.

This structuring of weight classes facilitates fair competition among lifters of similar body sizes and helps in maintaining a consistent competitive environment across various age levels and weight divisions. Understanding the existing weight categories is crucial for referees and athletes to ensure compliance with the rules during competitions.
