A scheduling algorithm assigns priority proportional to the waiting time of a process. Every process starts with priority zero (the lowest priority). The scheduler re-evaluates the process priorities every $$T$$ time units and decides the next process to schedule. Which one of the following is TRUE if the processes have no $${\rm I}/O$$ operations and all arrive at time zero?
A
This algorithm is equivalent to the first-come-first-serve algorithm.
B
This algorithm is equivalent to the round-robin algorithm.
C
This algorithm is equivalent to the shortest-job-first algorithm.
D
This algorithm is equivalent to the shortest-remaining-time-first algorithm.
