Which of the following are applications of linked lists?a.All of the aboveb.Chaining in hash tablesc.Implementing file systemsd.Binary tree implementation

All of the options mentioned are applications of linked lists.

a. All of the above: This option is correct because all the options listed below are applications of linked lists.

b. Chaining in hash tables: Linked lists are used in hash tables to handle collisions. When two different keys hash to the same index, the corresponding values are stored in a linked list at that index.

c. Implementing file systems: Linked lists are used in the implementation of file systems. Each file is a linked list of disk blocks, which are not necessarily adjacent on the disk.

d. Binary tree implementation: Linked lists are used in the implementation of binary trees. Each node of the tree is connected to its children nodes via links, forming a linked list.

So, the answer is a. All of the above.
