The information needs to be displayed to the user at the same time and the return value of the billing information contains the input for the tax information callout. Each endpoint might take up to two minutes to process.
How should a developer implement the callouts?

A. An HTTP REST callout for the billing callout and a Continuation for the tax callout
B. An HTTP REST callout for both the billing callout and the tax callout
C. A Continuation for both the billing callout and the tax callout
D. A Continuation for the billing callout and an HTTP REST callout for the tax callout

Answer: C

Explanation:
Using Continuation for both callouts is the optimal solution when you have long-running callouts in a Visualforce page, as it allows the page to wait for a long-running process without tying up server resources.
The Continuation pattern is specifically designed for scenarios where the request-response cycle could exceed the timeout limits.
