For a given reaction \[3A+B\to C+D\] the rate of reaction can be represented by [DCE 2000]

• A.                 \[-\frac{1}{3}\frac{d[A]}{dt}=\frac{-d[B]}{dt}=\frac{+d[C]}{dt}=\frac{+d[D]}{dt}\]
• B.                 \[-\frac{1}{3}\frac{d[A]}{dt}=\frac{d[C]}{dt}=K{{[A]}^{m}}{{[B]}^{n}}\]
• C.                 \[+\frac{1}{3}\frac{d[A]}{dt}=\frac{-d[C]}{dt}=K{{[A]}^{n}}{{[B]}^{m}}\]
• D.                 None of these
