Final answer:
An elite tennis player would most likely find personal injury insurance advisable due to the high risk of physical injury which could impact their career and income.
Step-by-step explanation:
In the context of personal injury insurance, the individual who may find it most advisable to hold such insurance is the elite tennis player. This is due to the high risk of injury inherent in the physically demanding nature of professional sports, as well as the potential lost income during recovery periods. In contrast, the lawyer, salesperson, and hair stylist face other types of risks that may not be as immediately impactful on their physical ability to perform their jobs. The lawyer and salesperson should indeed consider insurance, but their careers are less tied to physical prowess.
