Answer: B

Explanation:

Correct answer is Untill Successful scope can be implemented while calling backend API’s

The Until Successful scope repeatedly triggers the scope’s components (including flow references) until they all succeed or until a maximum number of retries is exceeded The scope provides option to control the max number of retries and the interval between retries The scope can execute any sequence of processors that may fail for whatever reason and may succeed upon retry
