you are right.
the correct ans is D
compression of CNIII, in combination with descending corticospinal and corticobulbar fibers occurs, as part of superior alternating hemiplagia.
B&C involveCN12&6 respectively,in cobination with corticospinal fibers.
wallenberg syn(lms) typically doesnt involve damage to corticospinal fibers.
