B. Loss of total surplus on units that are no longer traded but were worth more to buyers than they cost sellers.✓ 答案
C. The rise in producer surplus.
D. The area of consumer surplus that still remains.

Tax revenue is a transfer from buyers and sellers to the government, not a loss by itself. Deadweight loss is the surplus destroyed because some mutually beneficial units are not traded. Remaining consumer surplus is a gain that still exists, not the loss.
