[Moved] What will be the answer for this relay logic diagram?

[swethamenon]

Draw the relay logic diagram for a circuit that operates as follows:
A. When switch one (SW1) is closed, the green pilot light turns on.
B. When switch two (SW2) is closed, the yellow pilot light turns on.
C. When both SW1 and SW2 are closed, the green and yellow
pilot lights turn off, and the red and white pilot lights turn on.

I believe an Exclusive-OR gate will be in the middle somewhere.
