Answer

c. caspid and nucleic acid.

Work Step by Step

The basic anatomy of all viruses include an outer caspid composed of protein subunits and an inner core of nucleic acid. The nucleic acid can be DNA or RNA, but not both. The inner core may contain various proteins, but not necessarily. In some cases, viruses have an envelope, but this is not always the case. Therefore, the correct answer would be c. caspid and nucleic acid. All viruses consist of a caspid and nucleic acid.
