Worked Solution

Step 1: Analyze the circuit diagram. Step 2: The current leaves the battery, passes through Bulb B1 (main circuit). Step 3: The path then splits into two branches: one with Bulb B2 and one with Bulb B3. Step 4: This means B2 and B3 are in parallel with each other, while B1 is in series with the parallel pair.

Correct answer: Bulbs B2 and B3 are arranged in parallel to each other.
