BDigraphs
CAllomorphs
DDysgraphia
Answer:
B. Digraphs
Read Explanation:
A digraph is a combination of two letters (graphemes) that represent a single sound (phoneme).
Examples:
"ch" in chair
"sh" in ship
"th" in think
Phonemes → These are the smallest units of sound in a language, not letter combinations.
Allomorphs → Variations of a morpheme (smallest unit of meaning), not related to graphemes.
Dysgraphia → A learning disability affecting writing ability, unrelated to letter combinations.
