113. In queuing theory, the nature of the wait ing situation can be studied and analysed mathematically if
A.Complete detailg- of items in;waiting line are known
B.Arrival and waiting times are known and can be grouped to form a waiting ,line model
C.All variables and constants are known and form a linear equation the laws governing arrivals, service times, and the order in which the arriving units are taken into source are known
