Worked Solution

Step 1: Identify the circuit arrangement. The components are in a single continuous loop (series circuit). Step 2: If Bulb Y fuses, it creates a gap in the circuit. Step 3: An open circuit prevents electric current from flowing entirely, so no bulbs will light up.

Correct answer: Both Bulb X and Bulb Z will not light up.
