Which one of the following property is correct for a red-black tree? Every simple path from anode to a descendant leaf contains the same number of black nodes. If a node is red, then one children is red and another is black. If a node is red, then both its children are red. Every leaf node (sentinel node) is red.

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 $10,8,7,5,3,2,1$ $10,8,7,2,3,1,5$ $10,8,7,1,2,3,5$ $10,8,7,3,2,1,5$
