    C)  amorphous S

    D)  monoclinic S

    E)  plastic S

    Correct Answer: B

    Solution :

    When\[{{H}_{2}}S\]gas is passed through nitric acid, colloidal sulphur is formed as. \[{{H}_{2}}\overset{-2}{\mathop{S}}\,+\overset{+5}{\mathop{2HN{{O}_{3}}}}\,\xrightarrow{{}}2{{H}_{2}}O+\overset{+4}{\mathop{2N{{O}_{2}}}}\,+\overset{0}{\mathop{S}}\,\]
