Highest % weight in both Earth's crust and human body C. Oxygen III. Relative abundance is much higher in living organisms than in Earth's crust D. Nitrogen IV. Present in very little amounts in Earth's crust Choose the correct answer
Options
- AA-II, B-III, C-I, D-IV
- BA-I, B-III, C-II, D-IV
- CA-I, B-II, C-III, D-IV
- DA-IV, B-III, C-II, D-I
Correct answer
B. A-I, B-III, C-II, D-IV
Step-by-step solution
According to NCERT data on the comparison of elements present in non-living and living matter: Silicon (Si) is present at 27.7% in Earth's crust but its amount is negligible in the human body. (A-I) Carbon (C) and Hydrogen (H) have a much higher relative abundance in living organisms compared to the Earth's crust. (B-III) Oxygen (O) contributes the highest percentage weight in both the Earth's crust (46.6%) and the human body (65.0%). (C-II) Nitrogen (N) is present in very little amounts in the Earth's crust, but c
