In embryonic development, the duodenum rotates in which direction?

Explanation:
During early gut development, the foregut undergoes a clockwise rotation when viewed from the front. This twist accompanies the stomach’s rotation, and the duodenum follows by turning to the right. As a result, the duodenum shifts from a midline position toward the right side and becomes fixed behind the peritoneum (secondarily retroperitoneal). So the direction of rotation is to the right, which is why that option best fits.
