The term "morpheme" is formed from two parts:
"morph", which comes from the Greek word "morphē" (μορφή), meaning form or shape,
and the suffix "-eme", used in linguistics to mean a distinctive unit (like in "phoneme").
So, "morpheme" literally means a unit of form or a minimal meaningful unit in the structure of words. Since the root "morph" is of Greek origin, the correct answer is Greek.
