Which of the following is an example of a closed syllable?

A closed syllable is a syllable that ends with a consonant sound, which 'closes' the vowel sound and typically indicates that the vowel is short. In the example of "cat," the vowel 'a' is followed by the consonant 't,' making it a closed syllable. This structure ensures that the vowel sound is pronounced as short.

In contrast, other options illustrate different syllable types. "He" is an example of an open syllable, where the vowel sounds long because it is not followed by a consonant. "Open" also represents an open syllable where the first syllable has a long vowel sound. "Silo" contains an open syllable in its first part, as the vowel 'i' is not followed by a consonant, resulting in a long vowel sound. Thus, "cat" as a closed syllable is correctly identified due to its structure.
