In a Min-Heap, the node at index i has a value of 12, and the node at index i*2 + 1 has a value of 15. Which of the following statements is correct?

In a Min-Heap, the heap property dictates that the parent node must have a value smaller than its children. However, this condition is only required for the direct parent-child relationship, meaning that a child node can have a value greater than the parent node without violating the Min-Heap property. In this case, the parent node (12) is less than the child node (15), so the heap property is satisfied. The Min-Heap only ensures that the minimum value resides at the root of the heap, and all parent nodes must be smaller than their respective child nodes. Why Other Options Are Wrong : A) is incorrect because the structure is a valid Min-Heap since the parent node is smaller than the child node. C) is wrong as a Min-Heap does not require both children to be smaller than the parent, only the parent needs to be smaller than its children. D) is incorrect because rebalancing is not necessary in this case; the heap property is maintained. E) is incorrect since a Min-Heap allows for children to be greater than their parent, as long as the parent is smaller than its immediate children.
