A. Enduring
B. Durable

A means "lasting for a long time" which is more appropriate
However, "durable peace" is also a collocation according to Oxford Dictionary
I prefer A. B does not seem to me a likely collocation. Clive

durable peace and enduring peace have been used about equally during the past 100 years, but personally, I prefer enduring peace. I may be influenced too much by my familiarity with expressions like a durable fabric, a durable material, a durable finish (for furniture), or a durable suitcase, none of which are abstract concepts like peace.
