b. Reduce speed slightly, stay off the brake, and move to LP3.
Explanation:
When a vehicle is trying to pass you on the left, first you have to slow down your vehicle and move on the right side of the road. When the vehicle passed you safely so now you can go with the normal speed. If you did not slow down your speed so there is more chances of accidents on the road because the driver lost their control over the vehicles due to higher speed.
