Correct answer: D

Rationale: Bananas are an excellent source of potassium. They are a popular choice for increasing dietary potassium intake due to their rich potassium content. Apples, asparagus, and carrots do not contain as high levels of potassium as bananas. While these fruits and vegetables are nutritious, they are not as effective in addressing a potassium deficiency as bananas.
