What are escrow instructions given by one party at a time to the escrow agent called?

Escrow instructions are typically given by one party at a time, making the answer B Unilateral the most accurate. Option A: Bilateral and Option C: Multilateral refer to agreements or instructions given by two or multiple parties, respectively, making them incorrect. Option D: Non-binding implies that the instructions given are not legally enforceable, which is not true for escrow instructions, making it an incorrect option as well.
