Is the tree generated by Huffman encoding guaranteed to be f

Is the tree generated by Huffman encoding guaranteed to be full or complete?

Select one:

a. Full, because every non-leaf node is guaranteed to have two children

b. Complete because every node may not have two children

c. Neither, because the tree is based on the input and we have no guarantees about its structure.

d. Neither, because nodes may have more than two children so the tree is not binary

The correct option is a)Full, because every non-leaf node is guaranteed to have two children

Explanation: Huffman tree or huffman coding is optimal if it is full binary since every non-leaf node is guaranteed to have two children.

Huffman trees are used to encode longer frequent characters with less number of bits.
