If rate of reaction in terms of disappearance of `NH_3` is `-(d[NH_3])/(dt)`, for the reaction : `4NH_3(g) + 5O_2(g) rarr 4NO(g) + 6H_2O(g)` then which of the following expressions are correct for rate of the reaction :

Options

A. `Rate= -4/5 (d[O_2])/(dt)`
B. `Rate= 3/2 (d[H_2O])/(dt)`
C. `Rate= (d[NO])/(dt)`
D. `Rate= 4/5 (d[O_2])/(dt)`
