Question

Match the column (I) of minerals, column (II) of functions and column (III) of relative percentage and select proper option.

I	II	III
(L) Phosphorus	(P) For photosynthesis and ionic balance	(i) 6%
(M) Magnesium	(Q) In structure of RNA, DNA and ATP	(ii) 8%
(N) Chlorine	(R) Structural component of chlorophyll	(iii) 0.2%
(O) Boron	(S) Absorption and utilisation of calcium	(iv) 0.3%

• A. L-Q-ii, M-R-iii, N-P-i, O-S-iv
• B. L-Q-i, M-R-ii, N-P-iii, O-S-iv
• C. L-R-i, M-Q-ii, N-S-iii, O-P-iv
• D. L-Q-i, M-Q-ii, N-P-iv, O-S-iii

Answer 1

The correct option is D L-Q-i, M-Q-ii, N-P-iv, O-S-iii

Phosphorus - It is a constituent of RNA, DNA and ATP. Its amount is 6%.

Magnesium - It is structural component of chlorophyll. Its amount is 8%.

Clororine - It is involved in photosynthesis and ionic balance in cell. Its amount is 0.2%.

Boron - It helps in absorption and utilisation of calcium. Its amount is 0.3%.

So the correct answer is 'L-Q-i, M-R-ii, N-P-iv, O-S-iii'.
