To determine the correct answer, we need to understand which factors are linked to hypertension. Hypertension, or high blood pressure, can be influenced by various factors including diet and lifestyle choices.

To identify the factor linked to hypertension from the given choices, we can analyze each option:

a. Sodium: Excessive consumption of sodium is indeed linked to hypertension. High sodium intake can increase blood pressure levels in some individuals.

b. Vitamin supplements: While vitamin supplements are generally considered beneficial for overall health, excessive consumption is not necessarily linked to hypertension. However, certain vitamins and minerals, such as potassium and magnesium, may have a positive effect on blood pressure regulation.

c. Protein: Excessive consumption of protein is not directly linked to hypertension. However, it is worth noting that some high-protein diets may involve the consumption of foods (e.g., processed meats) that can contribute to hypertension due to their high sodium content.

d. Phytochemicals: Phytochemicals are compounds found naturally in plants that can have health benefits. Excessive consumption of phytochemicals is not typically linked to hypertension.

e. Carbohydrates: Excessive consumption of carbohydrates, particularly refined or processed carbohydrates, can contribute to weight gain and obesity, which are risk factors for hypertension.

Therefore, from the given options, the correct answer is a. Sodium.
