D. The lower ASCII codes represent basic alphanumeric characters and punctuation, while the higher ASCII codes are generally used for graphics and non-ASCII characters in documents Explanation: Lower ASCII codes (0-127) represent basic alphanumeric characters, punctuation, and control characters. These include standard letters (both uppercase and lowercase), digits, and some punctuation marks. Higher ASCII codes (128-255), also known as the extended ASCII set, are used for additional characters, which may include graphics symbols, accented characters, and other non-standard symbols that are not part of the basic ASCII set. Thus, in an encoded message with a combination of lower and higher ASCII codes, the lower codes will refer to basic characters and punctuation, while the higher codes will include a broader range of symbols, often including graphical and non-ASCII characters.

Graphics files and documents use non-ASCII characters made in word processors, spreadsheet programs, or database programs and sent as email attachments.
