B. Sodium
C. Iron
D. Vitamin D

Answers

It’s sodium
Explanation because to high of sodium can soak up too much liquid and make the blood thicker

The addition of sodium in the processing of canned foods or frozen meals is linked to hypertension.

Hypertension is when there is an increase in the blood pressure of an individual. When the blood pressure of a person is more than 140/90, then that person will be said to be hypertensive.

Sodium leads to an increase in the blood pressure of a person. When an individual takes too much salt, the body will have to hold extra water which will be required to wash the salt from the body of the person. In such case, the added water will then put stress on the heart of the person. This ultimately leads to increase in the blood pressure.

In conclusion, the correct option is B
