Hi dnadna,
Ans C
a)main clue here is 7 th n palsy with forehead involvement(LMN 7 symptom) can be seen only if it involves 7 nucleus in pons
b)left conjugate gaze palsy...due to involvement of 6th nerve
c)Lt eye failed to adduct on rt gaze : 6 th n sends input to opposite 3rd(thorugh MLF) which supplies medial rectus
d)muscle strength 3/5 with positive babunski on Rt: pons carries corticospinal fibers to the opposite side(before decussation at medulla)
hope this helps.......GL
