Which statement describes DC current?

Explanation:
Direct current flows in one direction. In DC, the electrical potential stays with a fixed polarity, so electrons move steadily in a single direction through a conductor. This unidirectional flow is what distinguishes DC from alternating current, which regularly reverses direction. The other statements describe circuit topology (multiple paths) or protective devices (overload protection), not the fundamental behavior of the current’s direction.
