Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
Bioelements are grouped into prime (major) elements and others. Prime elements make up most of the living matter.
Step 2: Prime elements
In the textbook classification, carbon, hydrogen and oxygen are the prime elements.
Step 3: Compare the options
Nitrogen, though important, is grouped separately, so it is the option that is not a prime element.
Final Answer:
Nitrogen is the option that is not a prime element. \[ \boxed{\text{(D) }\text{Nitrogen}} \]
