Question:Suppose the numbers 7, 5, 1, 8, 3, 6, 0, 9, 4, 2 are inserted in that order into an initially empty binary search tree. The binary search tree uses the usual ordering on natural numbers. What is the in-order traversal sequence of the resultant tree?

A: 7 5 1 0 3 2 4 6 8 9
B: 0 2 4 3 1 6 5 9 8 7
C: 0 1 2 3 4 5 6 7 8 9
D: 9 8 6 4 2 3 0 1 5 7

Ans: C
Solution: In-order traversal of a BST gives elements in increasing order. So answer c is correct.
