Answer:
C. Fatal
Step-by-step explanation:
A syllable is a part of a word that contains a single vowel sound and is pronounced as a unit. That vowel can but doesn't have to be surrounded by consonants.
The word whistle consists of two syllables - whi-stle. The words given in the options can be divided into syllables like this:
- ex-press
- be-gan
- fa-tal
- him-self
When we compare the second syllables in those words and the syllable -stle in whistle, we can see that the same vowel sound is present in the second syllable of the word fatal. This is why option C is the correct one.
