Which of the following is not a criterion for awarding a takedown?

A criterion that is not required for awarding a takedown is the concept that the majority of the defensive wrestler's weight must be supported by their hand(s). In wrestling, a takedown is awarded when the offensive wrestler brings the defensive wrestler's body to the mat in a controlled manner, demonstrating control and positioning, irrespective of how much weight is being supported by the defensive wrestler's hands.

The focus for awarding a takedown revolves more around the control exhibited by the offensive wrestler and the defensive wrestler's status relative to the mat, rather than a specific distribution of weight. The idea that the defensive wrestler needs to be "on the mat" is a valid criterion—as the takedown is defined by bringing them to a position where they are either on their back or in a position that clearly signifies that the offensive wrestler has gained control. Immediate reaction time doesn't factor into the decision of scoring a takedown; instead, it pertains more to how an athlete reacts during a match phase and doesn't directly relate to control or scoring criteria. Lastly, for a takedown to be awarded, the offensive wrestler must be in control of the situation, making this an essential criterion as well.
