The choice of sort codes in the SCARF reporting system is important because it:

a. Determines whether a high-level or a low-level programming language can be used to implement the system

b. Affects the decision on how long the interval must be before SCARF reports can be issued for audit scrutiny

c. Determines whether concurrent update can occur to the report file without compromising the integrity of the file

d. Determines whether application-specific data can be grouped together in some logical fashion
