Question

which prefix is not matched correctly to its meaning? dys: out of, outside hypo: deficient, decreased sub: under, less macro: large, abnormal size

Explanation:

The prefix "Dys" means "abnormal, difficult, or impaired", not "out of, outside". For example, "dysfunction" means abnormal function. While "sub" means "under, less" (e.g., "submarine" - under the sea), "hypo" means "deficient, decreased" (e.g., "hypoglycemia" - low blood sugar), and "macro" means "large, abnormal size" (e.g., "macrocephaly" - large head).

Answer:

Dys: out of, outside
