I agree with you ,but on the 2004 answer sheet it's the

first premolar

I dont know why

max 1st P articulates with distal fossa of mand 1st p............. if it will articulate with both teeth then ther will be an abnormal occlusion - max lingual cusp will cause plunging of food between mand 1st P and mand 2nd P.

Isn't the cusp to fossa relationship an older idea/concept for the rules of occlusion?
