Answer: A. Design/ pre construction.
Step-by-step explanation:
Architecture is the profession in charge of the design, projection, and construction of structures, such as houses or buildings, focusing on aesthetics and harmony of constructions. This career is very similar to civil engineering but differs in the fact that architecture focuses on design and engineering on construction.
In this case, Erick works on design or preconstruction, that is, drawing the plans of the houses that the structure for which he works is going to build. This is the first step in the construction process.
