The correct answer is: A. CRS
The Commissioner of Railway Safety (CRS) is the highest railway safety authority in India. The CRS is responsible for ensuring the safety of all railway operations in India. The CRS has the authority to grant permission for the reduction of the distance of 180 meters of VTO from the station.
The Railway Board is the apex body of the Indian Railways. The Railway Board is responsible for the overall management and administration of the Indian Railways. The Railway Board does not have the authority to grant permission for the reduction of the distance of 180 meters of VTO from the station.
The DRM is the Divisional Railway Manager. The DRM is responsible for the management of a railway division. The DRM does not have the authority to grant permission for the reduction of the distance of 180 meters of VTO from the station.
The distance of 180 meters of VTO from the station is a safety regulation. The regulation is in place to ensure the safety of passengers and railway employees. The regulation is not arbitrary and has been put in place after careful consideration of all factors.
The CRS is the only authority that can grant permission for the reduction of the distance of 180 meters of VTO from the station. The CRS will only grant permission if it is satisfied that the reduction of the distance will not compromise the safety of passengers and railway employees.
