Thermal decomposition of an orange solid A gives a green solid B, water and a colourless gas C. The gas reacts with chlorine to give an oily explosive liquid D. What are A, B, C and D?

Option: 1

A=K_{2}Cr_{2}O_{7},B=CrO_{3},C=O_{2},D=H_{2}O


Option: 2

A=K_{2}Cr_{2}O_{7},B=Cr_{2}O_{3},C=N_{2},D=NCl_{3}


Option: 3

A=(NH_{4})_{2}Cr_{2}O_{7},B=Cr_{2}O_{3},C=N_{2,}D=NCl_{3}


Option: 4

A=(NH_{4})_{2}Cr_{2}O_{7},B=CrO_{3},C=N_{2},D=NCl_{3}

(NH_{4})_{2}Cr_{2}O_{7}\rightarrow Cr_{2}O_{3}(Green)+4H_{2}O+N_{2} on heating.

N_{2}(g)+Cl_{2}(g)\rightarrow NCl_{3}(l) (oily explosive liquid)
