Solution
The correct options are
C Going up with uniform speed
D Going down with uniform speed
If the tension in the cable of the elevator is the same as the weight of the elevator, it means that the net force on the system is zero. Therefore, the net acceleration of the system will also be zero.
This means that the elevator is moving up or down with uniform speed.
Option C & D are correct.
