In double Distant signalling, outermost signal post is painted with ________. A. White & yellow B. Black & Yellow C. Green & Yellow D. None of these

The correct answer is: A. White & yellow

Double distant signalling is a system of railway signalling used to indicate the distance to the next signal. The outermost signal post in double distant signalling is painted with white and yellow stripes. This helps the driver to know how far away the next signal is and to slow down if necessary.

The other options are incorrect because they are not the colors used for double distant signalling. Black and yellow are used for distant signals, green and yellow are used for home signals, and none of these are used for double distant signals.
