Answer:
B.O(n).
Explanation:
Since the time complexity of visiting a node is O(1) in iterative implementation.So the time complexity of visiting every single node in binary tree is O(n).We can use level order traversal of a binary tree using a queue.Which can visit every node in O(n) time.Level order traversal do it in a single loop without doing any extra traversal.

I believe the answer to your question is going to be C. 20
Hope this helps:)
f(x) = x² + 1, x > 0
y = x² + 1
x = y² + 1
x - 1 = y²
√x - 1 = y
√x - 1 = f(x), x > 1
