Which statement accurately describes a penalty for balance beam when there is no acro flight series or only one D acro flight performed?

In gymnastics, particularly on balance beam, the composition of a routine is critical to scoring. When a gymnast does not include an acrobatic flight series or performs only one "D" acro flight, it results in a penalty. This penalty reflects the lack of required elements according to the code of points.

The absence of an acro flight series or the performance of just one D flight signifies that the routine does not meet the expected difficulty and composition requirements. Consequently, this results in a minimal deduction of 0.1 points for the failure to meet the routine's complexity. Therefore, the correct response to this question would not be the assertion that there is no penalty at all, as this would imply that the routine meets all the necessary requirements, which is not the case here.

The correct penalty indicates that a slight deduction is applied, which aligns with the scoring system in gymnastics that encourages and rewards more complex and challenging elements in performances.
