1. \(-\frac{\mathrm{d}[\mathrm{~A}]}{\mathrm{dt}}=\frac{1}{2} \frac{\mathrm{~d}[\mathrm{~B}]}{\mathrm{dt}}\)
2. \(-\frac{\mathrm{d}[\mathrm{~A}]}{\mathrm{dt}}=\frac{1}{4} \frac{\mathrm{~d}[\mathrm{~B}]}{\mathrm{dt}}\)
3. \(-\frac{d[A]}{d t}=\frac{d[\mathrm{~B}]}{\mathrm{dt}}\)
4. \(-\frac{\mathrm{d}[\mathrm{~A}]}{\mathrm{dt}}=4 \frac{\mathrm{~d}[\mathrm{~B}]}{\mathrm{dt}}\)

Answer

(B) - d [ ~A ] dt = 1 4 ~d [ ~B ] dt
