Heap is complete binary tree. To insert a new element, we put it at the end of the tree and move up towards root till heap property is satisfied. Here, $35$ comes as child of $15$, with the path $40-30-15-35$. So, we swap $15, 35$ and then $30, 35$ to get the new path $40-35-30-15$. So, new heap will be $40 \ 35 \ 20 \ 10 \ 30 \ 16 \ 17 \ 8 \ 4 \ 15$.
Correct Answer: $B$
