Which of the following statements best explains how the Shannon$-$Weaver model of communication could be applied to the challenges faced by the GC&CS$?$

Because the messages being sent were encoded, the Shannon$-$Weaver model, which focuses on encoding and decoding, is the most useful model for this situation.

The Shannon$-$Weaver model focuses on technological challenges and can easily be applied to the technical problems faced when using machines to break the codes.

People who were recruited for work at Bletchley Park were identified as educated, problem solvers, and good with language, all important elements of the Shannon$-$Weaver model.

The communications that were decrypted at Bletchley Park were a result of the intense focus on the development of people who likely understood the Shannon$-$Weaver model.
