Answer:

b. It allowed railroads to form a cross-country network.

Explanation:

Before the adoption of the Standart Gauge, there were many railroad gauges - such as Scotch, Common English & American, Easter countries, Scotch, Canadian Grand Trunk, Irish, etc -. This means that each railroad would use one type of gauge and the railroads would not be compatible.

Once the Standart Gauge was adopted, many railroads that were built by different companies were compatible which made possible to construct a cross-country network like the Transcontinental Railroad.
