Select the correct alternative from the given choices. The correct matching for the following pairs is (A) Disk scheduling (1) Round Robin (B) Batch processing (2) SCAN (C) Time sharing (3) LIFO (D) Interrupt processing (4) FIFO (A) $\mathrm{A}-3, \mathrm{~B}-4, \mathrm{C}-2, \mathrm{D}-1$ (B) $A-4, B-3, C-2, D-1$ (C) $A-2, B-4, C-1, D-3$ (D) $\mathrm{A}-2, \mathrm{~B}-1, \mathrm{C}-4, \mathrm{D}-3$

Implement Priority with round-robin scheduling algorithm, which schedules tasks in order of priority and uses round-robin scheduling for tasks with equal priority. 1. Priorities range from 1 to 10, where a higher numeric value indicates a higher relative priority. For round-robin scheduling, the length of a time quantum is 10 milliseconds. 2. The implementation of this project may be completed in either C/C++ or Java, and program files supporting both of these languages are provided in the source code in the following GitHub link: https://github.com/greggagne/osc10e/tree/master/ch5/project. The Java directory contains Java codes, and the POSIX directory contains C code. This link has several scheduling algorithms, but you just need to complete only one algorithm, Priority with round-robin. These supporting files read in the schedule of tasks, insert the tasks into a list, and invoke the scheduler. The schedule of tasks has the form [task name] [priority] [CPU burst], with the following example format: T1, 4, 20 T2, 2, 25 T3, 3, 25 T4, 3, 15 T5, 10, 10 Thus, task T1 has priority 4 and a CPU burst of 20 milliseconds, and so forth. It is assumed that all tasks arrive at the same time, so your scheduler algorithm does not have to support higher-priority processes preempting processes with lower priorities. In addition, tasks do not have to be placed into a queue or list in any particular order. There are a few different strategies for organizing the list of tasks, as first presented in Section 5.1.2. One approach is that a list could be ordered according to scheduling criteria (that is, by priority). One other strategy involves having a separate queue for each unique priority. It is also worth highlighting that we are using the terms list and queue somewhat interchangeably. However, a queue has very specific FIFO functionality, whereas a list does not have such strict insertion and deletion requirements.
