How shall we act when we observe a traffic light with a non-flashing yellow light?

A)We will pass with caution, giving way to the right and left.
B)We will stop as if it were a steady red.Correct
C)We will exercise extreme caution.
A non-flashing yellow light requires us to stop as if it were a steady red, unless at the moment it lights up the vehicle is so close to the stopping point that it is not possible to stop in conditions of sufficient safety.
If the traffic light were a flashing yellow light or two alternately flashing yellow lights, it would require drivers to exercise extreme caution and, where appropriate, give way. Furthermore, they do not exempt from compliance with other signs requiring stopping.
