In an array-based representation of a binary tree, the root node is stored at index 0.State true or false.a)Trueb)False

Step 1: Understanding Array-based Representation of a Binary Tree

In an array-based representation of a binary tree, we typically start storing the tree's nodes from index 0. This means that the root node of the binary tree is indeed placed at index 0, which is a common aspect of many programming languages and data structures.

Step 2: True or False Evaluation

Given the statement, "In an array-based representation of a binary tree, the root node is stored at index 0," we can evaluate it directly based on our understanding.

Step 3: Conclusion

Since the root node is indeed stored at index 0 in the array representation, the statement is true.

Final Answer

a) True
