Options Analysis: 1. Graph: A graph is not linear because it can have nodes connected in a non-linear way (e.g., cycles, branches). \[\] 2. Tree: A tree is a hierarchical structure, not linear. It branches out and does not maintain a single sequence. \[\] 3. Binary Tree: Binary trees are hierarchical structures and do not represent a linear relationship between elements. \[\] 4. Queue: A queue is a linear data structure because it maintains elements in a sequential order where the order of operations follows FIFO (First In First Out). \[\] Correct Answer: The Queue is a linear data structure. \[\] Correct Option: (d)
