Expert's answer
The protoplasm is also known as cytoplasm. By chemical analysis it has been found that protoplasm essentially consists of 34 elements out of which about 12 elements are supposed to be present universally. 99% of protoplasm is made of 4 basic elements, i.e., oxygen, carbon, hydrogen and nitrogen. Therefore, these are called major constituents of the protoplasm. 8 other elements (trace elements), present in quantities of less than 1% each, are sulphur, phosphorus, potassium, iron, magnesium, calcium, sodium and chloride.
Thus, the correct answer is (2) 6 elements
