Arrange the following events in the correct sequential order of how safety mechanisms operate when an insulation fault occurs in a metallic-body appliance (like an electric iron):\n\n1. Current leaks from the live wire to the metallic body of the appliance.\n2. The low-resistance earth wire channels the leakage current safely to the ground.\n3. The sudden surge of high current passes through the live wire and melts the fuse.\n4. The circuit is broken, preventing electric shock and fire.\n\nSelect the correct sequence:

Options:

• A: 2-1-3-4
• B: 1-3-2-4
• C: 2-3-1-4
• D: 1-2-3-4
