• A) The initial 90-degree counterclockwise rotation of the intestinal loop occurred, but subsequent rotational steps failed.
• B) The initial 90-degree counterclockwise rotation of the intestinal loop occurred, which was followed subsequently by another 180-degree counterclockwise rotation.
• C) Each limb of the intestinal loop rotated separately, with only the cranial intestinal limb rotating 90 degrees counterclockwise in the initial rotational step and only the caudal limb rotating 180 degrees counterclockwise during the second rotational step.
• D) The initial 90-degree counterclockwise rotation of the intestinal loop occurred, but the subsequent 180-degree rotational step was in the clockwise direction.
