Major minerals containing nitrogen are:
  • A
    $\text{DNA}$
  • B
    $\text{RNA}$
  • ✓
    $\ce{KNO_3, NaNO_3}$
  • D
    All of these
✓

Answer

Correct option: C.
$\ce{KNO_3, NaNO_3}$
Nitrogen gas makes up about $78%$ of the atmosphere by volume. There are relatively major minerals containing nitrogen as nitrates are 'saltpetre' $(\ce{NaNO_3})$ and $\ce{KNO_3}$.
