Which of the following is a plant-based source of polyunsaturated fat?

Tofu is a plant-based source of polyunsaturated fat, making it the correct choice. It is derived from soybeans, which are known to contain essential fatty acids, including omega-3 and omega-6 fats, that are categorized as polyunsaturated fats. These fats play a crucial role in heart health, brain function, and overall wellness, as they can help reduce bad cholesterol levels and lower the risk of cardiovascular diseases.

In contrast, butter, cheese, and chicken skin are animal-based products. These typically contain saturated fats, which can contribute to an increase in LDL cholesterol levels if consumed in excess. Recognizing plant-based sources of healthy fats, like those found in tofu, is important for promoting a balanced diet and improving overall health.
