The phrase "make much of" in the context of the sentence implies showing a high degree of attention, affection, or admiration towards someone. Therefore, option A, "now values Michael," is the most appropriate interpretation.

This suggests that Nancy's behaviour has changed because Michael has become rich, indicating that she now holds him in higher regard or places more value on their relationship due to his newfound wealth. It does not necessarily imply financial gain for Nancy or any change in their marital status.
