If the road surface or visibility is compromised in any way, such as by traffic congestion or bad weather, you must
a. drive at the posted speed limit
b. adjust your speed
c. use cruise control
d. stop and wait until the weather improves

I believe the answer is: b. adjust your speed

Bad weather could create a situation that compromise your driving process, such as the decrease in vision or the increase of slipperiness on the road. Because of this, you need to adjust and lower your speed during bad weather in order to prevent accidents.
