Worked Solution

Step 1: A circuit where components stay lit independently is a parallel circuit. Step [2-9]: In a parallel circuit, current has more than one path to flow. Step [2-9]: Therefore, a break in one path (fused bulb) does not stop the flow in the other path.

Correct answer: In parallel
