Final answer:
The definition of "development" in the CFR can vary depending on the context and without specific context, the exact Title cannot be determined. The CFR contains all federal rules and regulations, with Title 47 pertaining to the FCC.
Step-by-step explanation:
The Code of Federal Regulations (CFR) contains the rules and regulations for all executive departments and agencies of the US federal government. The term "development" could fall under various Titles of the CFR depending on the context in which it's being used. However, without a specific context, it's not possible to determine the exact Title where "development" is defined. It's also worth noting that the FCC's rules and regulations are located in Title 47 of the CFR, but this is specific to communications and may not necessarily contain a broad definition of development.
