Arrange the following stages of friction experienced by a heavy block on a rough horizontal floor in chronological order, starting from when the block is at rest with no force applied, to when a gradually increasing horizontal force is applied until it moves continuously: 1. Kinetic friction comes into play. 2. Static friction adjusts itself to equal the applied force. 3. Limiting friction is reached. 4. No frictional force acts on the block. Select the correct sequence:

Options:

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