An organic compound containing phosphorous on oxidation with \(\mathrm{Na}_2 \mathrm{O}_2\) gives a compound ' X '. This ' X ' when boiled with \(\mathrm{HNO}_3\) followed by treatment with a reagent gives yellow precipitate \(\mathrm{Y} . \mathrm{X}\) and Y respectively are

  1. A \(\mathrm{Na}_3 \mathrm{PO}_4,\left(\mathrm{NH}_4\right)_2 \mathrm{MoO}_3\)
  2. B \(\mathrm{Na}_3 \mathrm{PO}_4,\left(\mathrm{NH}_4\right)_2 \mathrm{MoO}_4\)
  3. C \(\mathrm{H}_3 \mathrm{PO}_4,\left(\mathrm{NH}_4\right)_2 \mathrm{MoO}_4\)
  4. D \(\mathrm{Na}_3 \mathrm{PO}_4,\left(\mathrm{NH}_4\right)_3 \mathrm{PO}_4 \cdot 12 \mathrm{MoO}_3\)
