Answer
Brief Explanations:
Architects focus on multiple aspects beyond aesthetics, including functionality, safety, and structure. The claim that they are "only" concerned with aesthetic appeal is incorrect. Other options correctly describe architectural elements: springing line connects arch spring points, corbel dome forms from rotating corbel arches, and keystone is the final, voussoir-holding piece.
Answer:
B. Architects are concerned only on the aesthetic appeal of architecture.
