Transportation vital to J.J. McAlester because B) It made the transport of his resources possible.

Explanation:

Known as the father of Eastern Oklahoma, JJ McAlester is often attributed to the thriving coal mining industry in the Pittsburgh county. JJ McAlester in 1869, having known of the coal outcroppings in the area, opened a store. It was thus necessary for the town to have excellent connectivity to other parts of the State.

The construction of the Missouri, Kansas and Texas Railway proved to be extremely rewarding for McAlester as the coal city was now connected to major hubs of trade and business. This ensured that all his resources could be sold to other cities rather than being bound to the small town of McAlester.

Later the east-west railroad proved to be even more beneficial as the same served the town’s rich coal fields. Transporting the coal across the country, the railways significantly improved the economy of the town.
