Which dermatome is on the front of both thighs?

Explanation:
Dermatomes map skin areas to spinal nerve roots, and the front of the thigh is innervated mainly by the L2–L3 roots, with L3 covering the larger portion down toward the knee. So L3 is the best single dermatome to describe the skin on the front of both thighs because it spans the most extensive anterior thigh surface. L2 is higher up near the groin and doesn’t extend as far down the thigh, while L4 and beyond cover lower leg and foot regions. The other options correspond to areas distant from the thigh (T1 in the upper trunk/arm region, C6 in the arm), so they don’t fit.
