What is the most performant way of implementing this requirement?

An insurance company is implementing a MuleSoft API to get inventory details from the two vendors. Due to network issues, the invocations to vendor applications are getting timed-out intermittently. But the transactions are successful upon reprocessing

What is the most performant way of implementing this requirement?
A . Implement a scatter-gather scope to invoke the two vendor applications on two different route
Use the Until-Successful scope to implement the retry mechanism for timeout errors on each route
B. Implement a Choice scope to invoke the two vendor applications on two different route
Use the try-catch scope to implement the retry mechanism for timeout errors on each route
C. Implement a For-Each scope to invoke the two vendor applications
Use until successful scope to implement the retry mechanism for the timeout errors
D. Implement Round-Robin scope to invoke the two vendor applications on two different routes
Use the Try-Catch scope to implement retry mechanism for timeout errors on each route
