Why did factory owners prefer to employ women a factory owner could pay women lower wages than men. b women worked harder than men. c women had better knowledge of machinery. d women would bring their children with them to work.

Factory owners preferred to employ women back in the Industrial age because they were able to get away with paying them less than they would if they had hired a man. Back then there weren't really any women's rights, so the factory owners could pay whatever they wanted to a woman, who were seen at the time as being inferior to men, and thus deserved lower pay. This overall saved the factory lots of money in the long run.
So I would think I would be A,
Hopefully that helps you :D ❤
