The most accurate answer regarding the impact of the Industrial Revolution on family structures would be:
d) separated work from home.
During the Industrial Revolution, many families moved from rural areas to cities to work in factories, which often meant that work was no longer done in the home. This shift changed family dynamics and structures, as daily life became more centered around industrial labor outside the home. While options a) and c) also reflect aspects of the Industrial Revolution's effects on families, option d) best captures the overarching change in the organization of family life during that period.
