  4. Silicon
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

  •  The four major structural elements in the human body by weight  (oxygen, hydrogen, carbon, and nitrogen), are usually not included in lists of major nutrient minerals.
  • As a group, minerals are one of the four groups of essential nutrients, the others of which are vitamins, essential fatty acids, and essential amino acids
  • The five major minerals in the human body are calcium, phosphorus, potassium, sodium, and magnesium All of the remaining elements in a human body are called "trace elements". The trace elements are sulfur, iron, chlorine, cobalt, copper, zinc, manganese, molybdenum, iodine and selenium. Hence, silicon is not a major nutrient for the body.
So, the correct answer is 'silicon'.
