Worked Solution

Step 1: Identify the observation (one bulb stays lit when the other is removed). Step 2: Recall circuit properties. In a parallel circuit, there are multiple paths for electricity. Step 3: If one path is broken, current can still flow through the other path. Step 4: Final Answer: In parallel.

Correct answer: In parallel
