Be careful here, to me this question is one of very tricky question. Answer is B and not A because A forces data type conversion from string to Integer/long.

The correct option is B. Add @PathVariable long accountId argument to the update() handler method. The @PathVariable annotation is used to bind a path variable from the request URI to a parameter in the handler method. In this case, the path variable is id, and the type is long. This means that the account id will be passed to the update() handler method as a long value
