Which word is an example of a diphthong?

Book
Cat
Coin
Tree

The correct answer is: Book

A diphthong is a vowel sound formed by the combination of two vowels in a single syllable. Some examples of diphthongs include "oy" in "boy" and "ie" in "pie". In this particular question, "Book" is the only word that contains a diphthong, the combination of the letters "oo". The other options do not contain any diphthongs, as they only have a single vowel sound in their syllables. Therefore, they are not considered examples of diphthongs.
