The Correct Option is C
Solution and Explanation
Step 1: The marked landmark is the umbilicus, which is the standard reference point for the T10 dermatome.
Step 2: The T10 dermatome lies at the intersection of the midclavicular line and the horizontal level of the umbilicus.
Step 3: By contrast, T8 lies halfway between the xiphoid process and the umbilicus, T9 lies at three quarters of that distance, and T11 lies midway between the umbilicus and the inguinal ligament.
Step 4: Because the marked area is at the level of the umbilicus, the correct dermatome is T10.
