B.Depth of water approaching a sea port
C.Cargo terminals at airport
D.Width between the tracks of a railway line

Answer 1

Hint:In the gauge of a railway track,we can see that there is a clear minimum vertical distance which can be found between the inner sides of the two tracks and this distance between the two tracks on the railway route is referred to as a railway gauge.

Complete answer:
There are four types of gauges in the railway system in India.
Broad Gauge: Among the railway gauges, the broad gauge line is one of the most widely used gauge in our country. It has an approximate track length of 108,500 km track and 60,430 km of route length. It is also known as Indian gauge and is the broadest gauge which is in use around the world.
Meter Gauge: Meter gauges were made in order to reduce the cost. The distance between two tracks in a meter gauge 1,000 mm (3ft 3 3/8 inches)
Narrow Gauge: Narrow gauges are constructed by keeping in mind the cost considerations. They are also referred to as narrow gauge or small lines because the distance between the two railway tracks are 2 ft 6 inches and 2 ft inches.
Standard Gauge: Standard gauges in India are mostly used in urban transport systems. The transit system includes metros,monorail and the trams. In this railway gauge, the distance between the two tracks is around 4 ft and 8 inches.

Hence, the correct answer is option (D).

Note: Railway connects one from different parts of the country to another. Presently, India has the fourth largest railway system in the world after the United States, China and Russia. It transports around 2.5 crore passengers daily.
