To find the correct answer, we need to understand what the transportation revolution of the 19th century involved. In the 19th century, there was a significant development and expansion of various modes of transportation, which transformed the movement of goods and people. The key modes of transportation during this period were cars, trains, boats, and planes.

To determine which commercial mode of transportation was not included in the transportation revolution of the 19th century, we can eliminate the options one by one.

A. Cars: Cars did not exist as a mainstream mode of transportation during the transportation revolution of the 19th century. However, they were developed and started gaining popularity towards the end of the 19th century.

B. Trains: Trains played a crucial role in the transportation revolution of the 19th century. They were widely used for both freight and passenger transport, connecting distant regions and facilitating trade and travel.
