Answer
Multiuser, multiprocess
Options - A. Multiuser, multiprocess - B. Single-user, multiprocess - C. Multiuser, single-process - D. Single-user, single-process Why - A. Correct — many users, and each of them running several processes, is the box UNIX was designed for. - B. This is a desktop: many processes, but only one person logged in. The twenty logins rule it out. - C. This would mean the machine runs exactly one process at a time while twenty people wait for it. Nothing in the description says that, and no such system was ever built. - D. This is MS-DOS. It fails both axes at once.
