Which reference standard?

@All.

Here it's saying about Road Marking, In IRC 35 2015, it clearly states that " Edge line provided all along the raised kerb, both median side or footpath/raised Kerb on shoulder side shall always have the setback distance to the extent possible which shall not be not less than 200 mm from the vertical face of kerb". So, the correct answer will be 20 cm.

Road markers or traffic signs are typically placed at a minimum distance of 50 cm from the edge of a kerb to ensure they are visible and do not obstruct pedestrian movement or pose a hazard to vehicles.

This standard helps maintain safety and functionality on the road.
