Worked Solution

Step 1: Identify the arrangement. B1 and B2 are in a parallel circuit. Step 2: Parallel circuits have multiple pathways for current to flow. Step 3: If B1 fuses, its specific branch is open, but the pathway through B2 remains closed. Step 4: Current continues to flow through B2, keeping it lit.

Correct answer: Bulb B2 will remain lit.
