Which statement about digraphs is true?

• A. Digraphs involve a single letter making a sound
• B. Digraphs may include three letters representing one sound
• C. Digraphs always produce two sounds
• D. Digraphs are two letters that produce one sound

Answer: (D)

Two letters can work together to make a single sound, and that is exactly what a digraph is. When you see letter pairs like sh in ship or ph in phone, the two letters combine to produce one sound rather than two separate sounds. That’s why this statement—two letters that produce one sound—is the best description of a digraph. The other ideas don’t fit: a single letter by itself makes a sound, a group of three letters can form one sound but would be a trigraph, and two letters can sometimes produce two distinct sounds rather than one single sound.
