Final answer:
The actual architect for the Wolf Point Chicago development is Chris Pemberton from Pelli Clarke Pelli Architects.
Step-by-step explanation:
The architect responsible for the new development at Wolf Point Chicago is none of the individuals listed as options in the question. The correct architect for the Wolf Point development is Chris Pemberton from the architecture firm Pelli Clarke Pelli Architects. Unfortunately, the options provided in the question: Santiago Calatrava, Cesar Pelli, Rem Koolhaas, and Carlos Arnaiz do not include the correct person or firm. Cesar Pelli was the founder of the firm, but Chris Pemberton is the specific architect for the Wolf Point project. It's also important to note that after the passing of Cesar Pelli, the firm was renamed to Pelli Clarke Pelli Architects.
