For the reaction, A+3B→2C+D which one of the following is not correct?

For the given reaction,A+3B→2C+DRate expression;−d[A]dt=−12d[B]dt=12d[C]dt=d[D]dtOption (A);Rate of disappearance of A = Rate of formation of D∴−d[A]dt=d[D]dtOption (B);Rate of formation of C = 23×  Rate of disappearance of B−12d[C]dt=−13d[B]dt∴d[C]dt=23d[B]dtOption (C);Rate of formation of  D =13× Rate of disappearance of B∴d[D]dt−13d[B]dtOption (D);−d[A]dt=12d[C]dt∴ Rate of disappearance of A is 12 times to that of rate of formation of C
