The most satisfying marriages are ones in which partner's attributes, interests, and goals ______.

A) complement one another
B) oppose each other
C) are kept separate from each other
D) interact with permission

When partners' attributes, interests, and goals complement each other, they are more likely to support each other, feel fulfilled, and create a harmonious relationship. Opposing each other or keeping their interests and goals separate can create conflict and tension in the relationship. Interacting with permission can be positive, but it is not as comprehensive as complementing each other in all aspects.
