Quizplus · Accepted Answer

Hydroxyapatite, a major compound in human bones and teeth, is composed of calcium, phosphorus, oxygen, and hydrogen. Therefore, the correct answer is option B, which includes all four of these elements. Option A includes potassium, which is not present in hydroxyapatite, and option C and E include helium, which is not a component of hydroxyapatite. Option D includes the correct elements but is not the best choice because it includes helium, which is not a component of hydroxyapatite.
