Which portion of the face is the most significant determinant of physical attractiveness in males:

A) Upper third (good hairline, thick brow, positive canthal tilt etc)

B) Middle third (hollowed cheeks, wide zygoma, narrow nose etc)

C) Lower third (sharp jawline, protruding chin, straight teeth etc)

I've been looking around but can't seem to find any good answer. This has been on my mind for a while now.
