The prefix Dia- denotes which meaning?

Explanation:
Dia- means through, across, or thoroughly. In medical terms this prefix often signals that something passes through a barrier or is done completely, as in dialysis (substances pass through a membrane) or diagnosis (reaching knowledge through examination). Because of this sense of passing through, the best meaning among the options is Through. The other ideas—around, across, or beyond—are represented by different prefixes, so they don’t fit as well with dia- in the common medical usage.
