no d.
clockwise or counterclockwise depends if one is looking at the top or bottom. And, "current". normally in physics, we consider the direction of current as the direction of a positive charge carrier, knowing that in metals current is electrons, going in the opposite direction of the mythical + charges.
If you use the positive current convention, then the right hand rule (thumb in direction of current), fingers then curl in the direction of magnetic field lines.
If the current in a wire is directed upward, what is the direction of the magnetic field produced by the current?
A. counterclockwise
B. clockwise
C. in the same direction as the current
D. in the opposite direction to the current
