Washington's earnest money requirements state:

Option A is incorrect because Washington does require an earnest money deposit as part of most real estate transactions. While the amount may be negotiable, a deposit is generally expected unless otherwise agreed.

Option C is incorrect because Washington law requires earnest money to be held by a neutral third party (typically an escrow agent or broker), not by the seller directly. This protects both parties' interests.

Option D is incorrect because Washington law specifically sets a 3-business-day timeframe for depositing earnest money after mutual acceptance. There is a clear time requirement in the state.
