The correct answer is A. It makes them stronger.
Step-by-step explanation:
In relationships, compromise or commitment means the people involved in a relationship are willing to work to maintain the relationship long-term; this means they cooperate to solve problems, support each other during difficult times and are honest about feelings, fears, etc. This quality is important in healthy relationships because it makes relationships last and be stronger as people who commit are more likely to overcome differences and obstacles. Indeed, for psychologists such as Robert J. Sternberg commitment or compromise is a key element for love and relationships. According to this, it can be concluded compromise makes relationships stronger.
