I had my old hot tub removed.

Now there is an unused 240v power coming out of the garage wall in a
conduit, down a few feet to the ground, then run along the edge of the house
about 15 feet, and end with a cable sticking out the conduit, temporarily
wrapped with electrical tapes.

The power is turned off at the breaker panel, of course.

What is the least amount of work to make this code compliant? Can I cut off
the cable flush with the conduit exit, and then put a conduit cap on it? Do
I have to put something at the end of the cut cables to cover the exposed
copper wires?
Pull the breaker or remove the wires from the breaker - or better
yet, both.
