Problem: I'm working on this massive LEGO castle, but I've hit a wall with these yellow pieces. Every time I try to snap them on, they either collide with the surrounding grey bricks or just won't seat properly. I must be looking at the wrong section of the manual. Could you help me cross-reference the assembly guide for this model and tell me which of the following areas is the correct designated spot for these parts?
Options:
A. Next to the four yellow squares on top of the flanking circular towers.
B. On the lower castle walls, serving as decorative exterior sconces.
C. Inside the four recessed grooves/studs in the center of the main building's grey roof.
D. At the very front of the grey roof, mounted on the railing-like elements.
E. Within the rock crevices of the unfinished ruin on the right side of the photo.
Please analyze the current build progress in the photo and the manual to provide the correct answer.
Answer: C
