Final answer:
The correct tort committed by the lifeguard is negligence. This occurs when someone fails to exercise reasonable care, resulting in harm to another person.
Step-by-step explanation:
The correct tort committed by a lifeguard who sees a struggling swimmer but ignores them because their shift is almost over is negligence. Negligence occurs when someone fails to exercise reasonable care, resulting in harm to another person. In this case, the lifeguard's failure to rescue the swimmer despite being aware of the danger constitutes negligence.
The lifeguard has a duty of care towards the swimmers and is expected to act reasonably to prevent foreseeable harm. By ignoring the struggling swimmer, the lifeguard breaches their duty of care. If the swimmer is injured or drowns as a result, the lifeguard may be held legally liable for their negligence.
This situation does not fall under intentional infliction of emotional distress or a violation of the Good Samaritan law as those involve different elements and circumstances.
