A Type C plug in Saint Vincent and the Grenadines?
Yes — it seats, though without a guaranteed earth.
Saint Vincent and the Grenadines's Type G and Type A and Type C and Type E and Type I and Type K sockets accept a Type C plug (Europlug). The plug is unearthed by design, so nothing is lost in translation. The wall delivers 230 V at 50 Hz (207–253 V within tolerance) — if your device isn't rated for that (look for "100–240 V" on the brick), an adapter won't save it.
