Four elements that comprise over 95% of the human body are carbon, phosphorus, oxygen, hydrogen calcium, phosphorus, hydrogen, nitrogen carbon, hydrogen, oxygen, nitrogen calcium, hydrogen, oxygen, nitrogen1

Option C, Carbon, Hydrogen, Oxygen, Nitrogen

Explanation:

The different chemical components and its constituents with in the human body areas follows –  

a)Oxygen – 65 percent

b)Hydrogen  - 10 percent

c)Carbon – 18 percent

d)Nitrogen – 3%

e)Calcium – 1.5 %

f)Phosphorus – 1%

g)Potassium 0.25 %

h)Sulfur – 0.25%

i)Sodium – 0.15%

h) Trace elements –  

Out of all these elements, the sum of oxygen, hydrogen, carbon and nitrogen is  

65 % + 10 % + 18 % + 3% = 96 %

The correct answer is option C, Carbon, Hydrogen, Oxygen, Nitrogen
