A) This is the correct answer. High dietary calcium intake is a common risk factor for certain types of kidney stones, particularly calcium oxalate stones. However, dietary calcium intake from food sources is not typically associated with an increased risk of kidney stones. Calcium supplements, on the other hand, may contribute to stone formation.

B) A low protein diet is not a significant risk factor for kidney stones. High-protein diets may be associated with an increased risk, but low protein intake is not a concern.

C) Adequate water consumption is essential to prevent kidney stones. Dehydration is a risk factor for stone formation, but excessive water consumption alone is not a significant risk factor.

D) While a sedentary lifestyle may be associated with other health risks, it is not a primary risk factor for kidney stones.
