C is the answer.
A: Although some women may have raised sons and daughters, they lived during a time when they taught their daughters to work in the home. Wrong - the expectation was for women to both work in the home AND raise children
B: Although some women had difficult upbringings, they lived during a time when working in the home was their only option. Wrong- these two things aren't really connected. And poor women were/are more likely to be working.
C: Although some women may have had doubts about working in the home, they lived during a time when doing so was often taken for granted. The first part is true (text evidence: "even though we may always be critical of some things in our past, time nearly always puts a halo around even a few of the disagreeable thing"). So is the second part- women only working in the home was (and is) taken for granted, as it was the norm. C is correct.
D: Although some women had been raised to consider individual careers, they lived during a time when they often opted to work in the home. Totally wrong- women were restricted and discouraged from having individual careers so it didn't happen often.
