Compound A (molecular formula `C_3 H_8 O`) is treated with acidifed potassium dichromate to form a product B (molecular formula `C_3 H_6 O`). B forms a shining sliver mirror on warming with ammonical silver nitrate, B when treated with an aqueous solution of `NH_2 NHCONH_2` and sodium acetate gives a product C. Identify the structure of C

Options

A. `CH_(3)CH_(2)CH=N NHCONH_(2)`
B. `CH_(3)underset(CH_(3))underset(|)(C)=NHHCONH_(2)`
C. `CH_(3)underset(CH_(3))underset(|)(C)=NCONHNH_(2)`
D. `CH_(3)CH_(2)CH=NCONHNH_(2)`
