The correct answer is: A. Broad Gauge
60 R rails are mostly used in Broad Gauge railways. Broad gauge is a type of railway track gauge with a distance between the rails of 1,676 mm (5 ft 5 1/2 in). It is the standard gauge in India, Pakistan, Bangladesh, Sri Lanka, Myanmar, Malaysia, Singapore, Thailand, Indonesia, Brunei, the Philippines, and Australia.
Metre gauge is a type of railway track gauge with a distance between the rails of 1,000 mm (3 ft 3 3/8 in). It is the standard gauge in most of Europe, Africa, and South America.
Narrow gauge is a type of railway track gauge with a distance between the rails of less than 1,000 mm (3 ft 3 3/8 in). It is used in some mountainous areas and for light railways.
