Final answer:
A cryptanalyst specializes in analyzing and deciphering messages written in code, so they would be most interested in files and messages that are coded. Option B is correct.
Step-by-step explanation:
A cryptanalyst would be most interested in examining files and messages written using some form of code. Cryptanalysts are professionals who analyze and decipher coded messages, without necessarily knowing the original content.
Therefore, their expertise is particularly relevant to coded documents rather than information that appears on a computer screen, business records in a foreign language, or records of pharmaceutical and medical offices, which would require different kinds of expertise to examine, such as IT professionals, linguists, and health records managers, respectively.
A cryptanalyst will be most interested in examining files and messages written using some form of code. Cryptanalysts are experts in decoding and deciphering encrypted information to uncover its meaning. They analyze code systems and try to break them to retrieve the original message. By studying files and messages written in code, cryptanalysts can uncover hidden information and understand the intentions behind the communication.
