What is the penalty for a 2 element acro flight series with a C salto?

In this context, a 2 element acro flight series that includes a C salto does not incur any penalty if performed correctly as per the current code of points for Level 10 gymnastics. The rules for acrobatic series allow for a series of two elements to be connected, with the requirement that at least one of these elements is a salto. Since the series includes a C salto, which is considered an acceptable difficulty level, it fulfills the requirements without any deduction.

Additionally, when evaluating acro flight series, penalties are enforced for failing to perform the required elements or connections properly or if the series does not meet the necessary difficulty requirements. However, in this case, since the series meets the criteria without any mistakes, it is awarded no penalty.

The other options represent potential deductions that would apply under different circumstances, such as insufficient connection, incorrect element execution, or a lack of required artistry or difficulty. However, these conditions are not applicable in this scenario, confirming that the penalty remains at zero.
