Lumbar plexus mainly innervates:
Go with C — Anterior thigh and abdominal wall. Within Peripheral Nervous System, that statement lines up with the standard definition and the usual exam wording you’ll see. In plain terms, the functional job described in the stem is exactly what Anterior thigh and abdominal wall does in Peripheral Nervous System. Holding that picture in mind makes Anterior thigh and abdominal wall feel natural rather than something you only memorise. Link the term to a real body example (organ, tissue, or ion flow) so the idea stays concrete under exam pressure. A short mental diagram helps — start from stimulus or structure, follow the pathway, and stop at the functional result described by Anterior thigh and abdominal wall.
