Introduction:
A binary tree is a hierarchical data structure in which each node has at most two children, known as the left child and the right child. It is a commonly used data structure in computer science and is used to represent hierarchical relationships between elements.
Explanation:
The correct answer is option 'B' - each node in a binary tree can have at most three children. Let's understand why this is true and why the other options are not correct.
a) Each node can have at most two children:
This statement is partially correct. In a binary tree, each node can have at most two children - a left child and a right child. However, it can also have fewer children. For example, leaf nodes have no children, and some internal nodes may have only one child.
b) Each node can have at most three children:
This statement is correct. In a binary tree, each node can have at most three children - a left child, a right child, and a middle child. This is known as a ternary tree. However, it is important to note that a binary tree specifically refers to a tree with at most two children per node.
c) Each node can have an arbitrary number of children:
This statement is incorrect. If a tree allows an arbitrary number of children per node, it is called a general tree or an n-ary tree, not a binary tree. In a binary tree, the number of children per node is limited to at most two.
d) Each node must have exactly two children:
This statement is incorrect. In a binary tree, nodes can have zero, one, or two children. Leaf nodes have no children, while internal nodes can have one or two children.
Conclusion:
In summary, a binary tree is a hierarchical data structure in which each node can have at most two children - a left child and a right child. Option 'B' is the correct answer as it correctly states that each node in a binary tree can have at most three children.
