Which option shows a vowel digraph?

• A. Er
• B. Br
• C. St
• D. Oa

Answer: (D)

A vowel digraph is two vowels written together that produce one sound. The pair “oa” has two vowels in a row, and in many words this combination makes a single vowel sound, as in boat or coat. That’s exactly what a vowel digraph is: two vowels working together to create one sound. The other options don’t fit because they’re not two vowels in a row. They’re either two consonants (which don’t form a vowel sound together) or a vowel plus a consonant, which isn’t two vowels forming one sound.
