Where's the person that the question is talking about?
Answer: The drift velocity is the average velocity that a particle, such as an electron, attains due to an electric field. It can also be referred to as axial drift velocity. In general, an electron will 'rattle around' randomly in a conductor at the Fermi velocity.
Answer:
the velocity is 4 ms, if it asked for change it be 0 m/s but its asking for velocity so option 4, 4m/s
