Why wouldn't Taylor allow Victoria to ride King?

Taylor’s decision not to allow Victoria to ride King stems from her belief that Victoria may not possess the necessary skills or dedication to handle the situation well. This reflects a concern about the compatibility between Victoria’s current abilities and the expectations involved in riding King, who may require a more experienced or committed rider.

While one might consider the other choices, they don't fully capture the specific reasoning behind Taylor's choice. For example, nervousness, fear of injury, or lack of prior experience are certainly important factors but do not directly address Taylor’s evaluation of Victoria's overall capability and commitment to riding. The emphasis on being "good" or "dedicated" highlights Taylor's priority for safety and competence on the horse, which is why this choice stands out as the correct rationale.
