  2. Btraded between a market maker and the public at the published quote
  3. Cbought and sold so that there is no real change in the security's beneficial ownershipcorrect
  4. Dpurchased on margin and immediately pledged as collateral for a separate loan
Why C is correct

A wash trade involves buying and selling the same security with no genuine change in beneficial ownership, creating a misleading appearance of trading activity. The 30-day repurchase rule describes the tax wash-sale rule, which is a separate concept.
