Answer:

The maximum number of children a node can have in a binary tree is 2.

Each node in a binary tree has at most two child nodes. The maximum depth of any node in a binary tree is “log n.” A depth-first search algorithm will always complete its traversal, where the visiting order is such that each child comes after all parents up to and including the current node. Binary trees cannot be infinite or cyclic, so there must be some value for which they eventually quit growing larger.
