Final answer:
Upon analysis of each set of words, none of the provided sets (A, B, C, or D) exclusively contain words with consonant digraphs. Each set contains at least one word with a consonant blend, which does not meet the criteria of having only words with consonant digraphs.
Step-by-step explanation:
The student's question is asking which set(s) of words contain only words with consonant digraphs and do not contain any words with blends. A consonant digraph is a pair of consonants that make a single sound, such as ch in chip or whip, while a blend is a combination of two or more consonants where you can still hear each individual letter's sound, such as sl in slip or cl in clap. Considering this, let's analyze each set:
- A. Chip, whip, slip - slip has a blend (sl), so this set does not qualify.
- B. Stop, clap, trap - all words contain blends (st, cl, tr), so this set does not qualify.
- C. Grab, flag, slam - all words contain blends (gr, fl, sl), so this set does not qualify.
- D. Swim, drag, spin - all words contain blends (sw, dr, sp), so this set does not qualify.
Therefore, none of the provided sets A, B, C, or D consist exclusively of words with consonant digraphs without any blends.
