Which of the following prefixes originates from the Greek language?

The correct answer is the choice that includes "arthr," "bio," and "crac" as these prefixes have Greek origins. Each of these prefixes can be traced back to Greek roots: "arthr" comes from the Greek word "arthron," meaning joint; "bio" stems from "bios," meaning life; and "crac" derives from "kratos," meaning power or strength. This indicates their use in forming terms related to biology, arthropods, democracy, and various other fields.

In contrast, the other options consist of prefixes derived primarily from Latin. For example, "act," "acu," and "aud" are Latin prefixes that relate to action or hearing. Similarly, "dic," "duct," and "dur" also come from Latin, with meanings associated with saying, leading, or hardening. The last option includes S, -ing, and -ed, which are not prefixes but rather textual elements or inflections in English grammar.

Understanding these origins helps in grasping the meanings of various English vocabulary terms, reflecting the influence of Greek and Latin languages on English word formation.
