On reaching a roundabout we encounter this sign. What should we do if we intend to change direction to the left?

A)We cannot change direction to the left because it is prohibited.
B)We will turn leaving the roundabout on our left.Correct
C)We will turn leaving the roundabout on our right.
The sign indicates the obligation to drive in a circular direction leaving the centre of the intersection on the left. Even in the absence of said sign, since it is a roundabout we must act in the same way.
Therefore, to turn left we must go around the central obstacle and leave the roundabout on our left.
