Which is correct, does your or do your?

Could you please clarify for me which form of the verb is more appropriate in this context: "does your" or "do your"? I'm a bit confused about the correct usage, especially when referring to a plural noun or pronoun. Could you provide an example sentence to illustrate the proper usage of each form? Additionally, could you explain the grammatical rule behind this distinction? I'd appreciate your guidance on this matter.
