The FAR is Codified in:

The Federal Acquisition Regulation (FAR) is codified in Title 48 of the U.S. Code of Federal Regulations. This title organizes regulations concerning federal procurement and the acquisition process, detailing how federal agencies must conduct their purchasing. The FAR establishes uniform policies and procedures for the acquisition of goods and services by federal agencies, thereby promoting consistency, efficiency, and transparency in government contracting.

The choice that refers to Title 46, Title 47, or Title 49 corresponds to other areas of regulation. Title 46 deals with shipping, Title 47 focuses on telecommunications, and Title 49 is concerned with transportation. Therefore, recognizing that the FAR is specifically designed to guide federal procurement practices helps clarify why it is codified in Title 48.
