Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
In an art gallery, a valuable painting is displayed in Room A. The curator decides to move the painting to Room B for better lighting. Security Guard 1 witnesses the move but accidentally tells Security Guard 2 that the painting was moved to Room C. Meanwhile, Security Guard 3 overhears their conversation and assumes the painting is now in Room D due to a misunderstanding. Where does each person involved believe the valuable painting is located? Respond very briefly.

### Response:

The curator knows the painting is in Room B because they decided to move it there for the lighting. Security Guard 1 also believes the painting is in Room B, as they witnessed the actual move. Security Guard 2, however, thinks the painting is in Room C because they were mistakenly informed of that location by Security Guard 1. Security Guard 3 believes the painting is in Room D due to their own misunderstanding of the conversation between Security Guards 1 and 2.
