Which of these is the strongest claim?

C is the strongest claim because it takes a clear, specific position: a strong circle of friends is what defines success. It also gives reasons for that position—friendship brings happiness, belonging, and support for overcoming obstacles—so it can be developed with evidence. B is too broad and absolute, while A is more cautious and focuses on one possible benefit of friendship rather than making as direct an argument about success.
