The correct option is B Simulation

The most useful applications of queues. Priority queues and linked lists is in simulation.

In the simulation we want to process events in the order that they occur. The priority queue is a natural data structure for storing events in a specified order as they come in.

Priority queue:-

A priority queue is an abstract data type which is like a regular queue or stack data structure, but where additionally each element has a "priority" associated with it. In a priority queue, an element with high priority is served before an element with low priority.

A priority queue is different from a normal queue, because instead of being a “first-in-first-out”, values come out in order by priority. It is an abstract data type that captures the idea of a container whose elements have “priorities” attached to them.

Linked list:-

A linked list is a linear data structure where each element is a separate object. Each element of a list is comprising of two items the data and a reference to the next node. The last node has a reference to null. The entry point into a linked list is called the head of the list.
