Which of the following vaults are eligible for a bonus of +0.1?

The eligibility for a bonus of +0.1 in gymnastics vaulting primarily refers to the performance of vaults that are assigned a starting value of 10.0, particularly when they are executed without any falls or spotting. This means that if a gymnast successfully performs a vault with a starting value of 10.0 in a clean manner, they are rewarded with the bonus, recognizing their ability to perform difficult skills with precision and control.

The focus on the vault's starting value highlights the significance of the gymnast's choice of vault and execution quality. It does not pertain to vaults with a lower starting score or to the specific types of vaults, such as whether they are Yurchenko vaults or not. This option emphasizes the importance of performing a high-value vault cleanly rather than the specific elements or styles involved.
