The answer is: D. By replacing steam, electricity enabled artificial lighting, which expanded factory work hours and production.

Compared to steam technology, production generated by electricity had significantly lesser cost and far easier to sustain.

This make factory able make the final price of the product become cheaper, had enough capital to expand factory work hours and production and improving the safety standard for the workers who had to work in the factory.
