Answer 1

Correct Answer - Option 1 : 1, 2 and 3 only

Sorting cant minimize the storage needed so option (1) is correct.

Sorting- it is a process of arranging items systematically.

Applications of  sorting are following:

• Searching -  Search preprocessing is the single most important application of sorting.
• Element uniqueness – we can find duplicate items present in the set.
• Frequency distribution – we can find the number of times a particular item used in set.
• Selection – we can find the kth largest or kth smallest number by using sorting.
