Which of the following represents the lowest value part score?

The lowest value part score in gymnastics represents the least amount of credit a gymnast can receive for a skill or combination of skills performed. In this context, a score of 0.1 is the only option that denotes the smallest increment on the scoring scale, as part scores often start from this baseline for minor deductions or lower-level skills. Each of the other options reflects higher values that would be awarded for more significant elements or combinations that meet greater execution standards. Therefore, choosing 0.1 correctly identifies it as the lowest part score in this question.
