68. Which of the following words contains at least one digraph?

Answer: B

Explanation:

Rough contains at least one digraph.

The word "Rough" includes the digraph "gh," which represents a single sound. This characteristic qualifies it as containing at least one digraph.

A) Corn

The word "Corn" does not contain any digraphs. Each letter in "Corn" represents a distinct sound without combining to create a new phoneme.

B) Rough

"Rough" is the correct choice because it contains the digraph "gh." In this case, "gh" represents the /f/ sound, making it a clear example of a digraph in use.

C) Frankly

The word "Frankly" does not contain any digraphs. Each phoneme in "Frankly" is represented by a single letter or a typical letter combination, without any pairs that create a new sound.

D) Capitalize

"Capitalize" does not contain a digraph either. The sounds in "Capitalize" are represented by individual letters or standard letter combinations, without any pairs that form a unique phoneme.

Conclusion

The word "Rough" is definitively the correct answer as it contains the digraph "gh," which produces a distinct sound that aligns with the definition of a digraph. All other options fail to meet this criterion, as they lack any letter combinations that create new phonetic sounds.
