Answer is (A)....whenever insertion will be done in heap ,it will always inserted in last level from left to right.so we insert $1$ and $7$ as a child of node $5$ now we perform heapify algorithm until heap property will satisfied..and then we get the heap whose level order traversal is $10,8,7,3,2,1,5$.
Initial heap
After insert of $1$
After insert of $7$
