In view of the red traffic light, may the blue car change direction to the right?

A)Yes, it cannot continue straight ahead but it may change direction both to the right and to the left.
B)No.Correct
Even though the traffic light is on the other side of the intersection, it must be obeyed in the same way as if it were located before the intersection. Therefore, the vehicle must stop before entering the intersection and wait until the traffic light allows it to proceed.
