Which of the following data structures stores elements in a non-linear relationship?

Correct Answer (Detailed Explanation is Below)

E. None of the above

Detailed Explanation

Explanations:

A non-linear data structure stores elements in a hierarchical or network relationship, not sequentially.

Linear data structures

Elements are arranged in sequence (one after another):

• Stack

• Queue

• Array

These are linear, not non-linear.

Non-linear data structures

Examples:

• Tree

• Graph

Check the options

• (A) Stack → Linear ❌

• (B) Queue → Linear ❌

• (C) Array → Linear ❌

Since none of the given options are non-linear, the correct answer is:

✅ (E) None of the above.
