$A$ current of $5 \,A$ is passing through a metallic wire of cross-sectional area $4 \times 10^{-6} \,m^{2}$. If the density of charge carriers of the wire is $5 \times 10^{26} \,m^{-3}$, the drift velocity of the electrons will be:
- A$1 \times 10^{2} \,ms^{-1}$
- B$1.56 \times 10^{-2} \,ms^{-1}$
- C$1.56 \times 10^{-3} \,ms^{-1}$
- D$1 \times 10^{-2} \,ms^{-1}$
