Question

The British Industrial Revolution and the American Industrial Revolution were connected by

occurring simultaneously, though they were independent of each other
subsidies from British parliament funding both
critical collaboration between the Scottish James Watt and the American Benjamin Franklin
Samuel Slater memorizing plans from England and bringing them to the United States

Answer 1

Samuel Slater memorizing plans from England and bringing them to the United States.

This is the most accurate answer as Samuel Slater, a British immigrant to the United States, memorized the design of textile mills and spinning machines from Britain and built similar machines in the United States, helping to kickstart the American Industrial Revolution. The British Industrial Revolution occurred earlier and independently of the American Industrial Revolution, and while there may have been some indirect connections between the two, such as the exchange of ideas and technology, they were largely separate phenomena.
