This a prohibition sign that indicates it is forbidden to turn to the right, which in spanish is Prohibido girar a la derecha or No gires a la derecha.
The other options are <u>incorrect</u><u> </u>because are not according to the image or the sign:
No gires a la izquierda means Do not turn to the left (It is forbidden to turn to the left)
No gires derecho and No gires recto<u>are illogic in spanish</u>, because the words girar (to turn) and recto/derecho(straight) do not match each other with the context.
