Final answer:

The direction of the induced current in a coil that experiences a changing magnetic field can be deduced using Lenz's law and the right-hand rule. For a counter-clockwise induced current viewed from above, the top edge (option C) of the coil will rise up.

Step-by-step explanation:

The question relates to determining the direction of an induced current in a coil when a magnetic field is changing. According to Lenz's law, the induced current will create a magnetic field to oppose the change that produced it. Using the right-hand rule, if the current is induced in a counter-clockwise direction, this means that you can point your right-hand thumb upwards (towards yourself if you are facing the coil), with your fingers pointing in the direction of the induced current.



Therefore, if we assume that the coil lies flat on a horizontal plane, and we observe it from above, the induced current flowing counter-clockwise implies that the top edge of the coil is moving towards you, causing it to rise up.
