Answer 2

The correct answer is B.

You may be driving at the posted speed limit and still receive a ticket if the posted speed  at that particular time when you're driving.

In such cases, it is advisable to reduce your speed and drive under ( or well under ) the posted or recommended speed. It is done as a measure to avoid accidents and unnecessary deaths.
