Sick individuals often experience altered taste sensations primarily due to the side effects of medications and the physiological changes brought on by illness. When the body is fighting an infection or dealing with a chronic disease, inflammation can affect the taste perception by altering the way taste buds respond to different flavors. Moreover, certain medications used to treat illnesses can have direct impacts on taste, leading to distortions or reductions in the ability to taste properly. This can result in flavors being perceived as bitter, metallic, or otherwise unpleasant, contributing to changes in appetite and dietary preferences.

In contrast, high levels of physical activity do not typically affect taste sensations in a way directly related to sickness. Normal functioning of taste buds refers to the healthy state of taste perception, which is generally not the case in sick individuals, as their taste sensation is often disrupted. Lastly, increased appetite might be a response to certain situations, but it does not explain the underlying reason for altered taste sensations during illness. The changes in taste are primarily linked to the body's response to illness and medication, making the third option the most accurate.
