When using the critical ratio ( CR ) priority sequence rule:
a. a ratio of less than “1.0” implies that a job has a priority over a job with a ratio of more than “1.0”.
b. a ratio of more than “1.0” implies that a job has priority over a job with a ratio of less than “1.0”.
c. the job with the earliest ‘due date’ is scheduled first.
d. none of the above.
