Which combination will yield a bonus of 0.4 CV?

The combination that yields a bonus of 0.4 Connection Value (CV) is founded on the criteria for earning connection bonuses in gymnastics routines. In this context, the correct answer involves a sequence that includes elements of varying difficulty that successfully connect to enhance the overall value of the routine.

In option C, the combination includes two C-level leaps and a D-level jump. Since the connection of elements of differing difficulty levels (in this case, two C-level leaps and a D-level jump) satisfies the requirements for additional bonus points, this combination effectively maximizes the potential CV awarded.

This balance and variety in difficulty levels facilitate achieving a higher bonus, specifically when combinations include elements that are immediately connected and meet the specified levels. Since the rules often stipulate specific combinations of elements leading to additional bonuses, the selection of diverse element levels is pivotal in maximizing score potential.

The other choices do not meet the established connection criteria or do not maximize the difficulty required to achieve the 0.4 CV bonus. Thus, option C stands out as the effective combination for obtaining the desired bonus.
