A priority queue is implemented as a Max-Heap. Initially, it has 5 elements. The level-order traversal of the heap is: 10, 8, 5, 3, 2. Two new elements 1 and 7 are inserted into the heap in that order. The level-order traversal of the heap after the insertion of the elements is:

Initially, the heap elements in level-order (array representation) are:

1. Insert 1:

   • 1 is added at index 6 (as the left child of node 5 at index 3).

   • Since $1 \le 5$, no swapping is needed.

   • Heap array becomes: $[10, 8, 5, 3, 2, 1]$

2. Insert 7:

   • 7 is added at index 7 (as the right child of node 5 at index 3).

   • Heap array before bubbling up: $[10, 8, 5, 3, 2, 1, 7]$

   • Compare 7 with its parent 5: since $7 > 5$, swap 7 and 5.

   • Heap array becomes: $[10, 8, 7, 3, 2, 1, 5]$

   • Compare 7 with its new parent 10: since $7 \le 10$, heap property is satisfied.

The resulting level-order traversal is 10, 8, 7, 3, 2, 1, 5, which corresponds to option (A).
