A developer is debugging an Apex-based order creation process that has a requirement to have three savepoints, SP1, SP2, and SP3 (created in order), before the final execution of the process.
During the final execution process, the developer has a routine to roll back to SP1 for a given condition. Once the condition is fixed, the code then calls a roll back to SP3 to continue with final execution. However, when the roll, back to SP3 is called, a runtime error occurs.
Why does the developer receive a runtime error?

• A.The developer used too many savepoints in one trigger session.
• B.The developer should have called SP2 before calling SP3.
• C.The developer has too many DML statements between the savepoints.
• D.SP3 became invalid when SP1 was rolled back.
