A

The correct answer is D (too much calcium) because while calcium is bone strengthening and essential for a healthy lifestyle, too much of it can lead to negative repercussions, as it builds up in the body.

Explanation:

These health effects can include the contamination of the urinary tract due to an overburdening of the bladder, abnormally high blood pressure, and a kidney infection, as well as flank pain.

Incorrect answers A and B, concerning potassium, are related more to heart pressure and nausea, while answer C is linked only to lessened muscle functioning.
