Correct answer is (b) over riding

Explanation: Metre gauge is the system of narrow gauge railways and tramways with a track gauge of 1,000 mm (3 ft 3\(\frac{3}{8}\) in). It has installations of around 95,000 kilometres (59,000 mi) in the world. It is the main gauge in some countries.

Broad gauge railways use a track gauge (distance between the rails) greater than the standard gauge of 1,435 mm (4 ft 8\(\frac{1}{2}\) in).
