Which term is defined as a circuit with two or more paths for current, where (-) terminals are connected to each other and (+) terminals are connected to each other?

Explanation:
The concept here is how current can have multiple paths and how components are wired together. A parallel circuit is defined by connecting the components across the same two points, so all the negative terminals are tied together and all the positive terminals are tied together. That creates two or more paths for current to flow from the source, and each path sees the same voltage across it. This is exactly what the description describes—the circuit provides multiple paths with common negative and common positive connections. Open circuits have breaks in the path and no complete loop for current. A resistor is just a single component, not a network with multiple branches. Semiconductors describe materials or devices, not the way a circuit is arranged.
