Explanation:

The Second Industrial Revolution (also known as the Technological Revolution) occurred in the decades following the American Civil War (which ended in 1865). The early 1800s was the time of the First Industrial Revolution, before the American Revolution (late 1700s) is too early, and the early 1900s is after the main period of the Second Industrial Revolution's peak. So the correct option is the one about decades following the Civil War.

Answer:

B. In the decades following the Civil War (assuming the options are labeled A, B, C, D with A: In the early 1800s, B: In the decades following the Civil War, C: Before the American Revolution, D: In the early 1900s)
