The correct option is (b) adjust your speed.

Further explanation:

On the road when road surface or visibility is compromised in any way, such as by traffic congestion or bad weather, you must adjust your speed.  Bad weather decreases the vision of the driver and makes roads slippery which increases the chances of an accident so it is suggested that one should adjust his speed in bad weather. In traffic congestion also, one should drive slowly and with safety.

WHY SHOULD ONE ADJUST HIS SPEED IN TRAFFIC CONGESTION AND BAD WEATHER?
