There is a typo in set 2 which I shall ignore.

2a is incorrect. You need to include ‘who’ as in 2.

2c doesn’t make much logical sense. She is not lazy due to the fact that she avoids chores. It is more likely that she would avoid chores because she is lazy. For this reason, ‘and’ would work but ‘because’ doesn’t.
