Public Class ClientServiceImpl Implements ClientService { @Transactional(propagation=Propagation

public class ClientServiceImpl implements ClientService { @Transactional(propagation=Propagation.REQUIRED) public void update1() { update2() ; } @Transactional(propagation=Propagation.REQUIRES_NEW) public void update2() { // ... } You are using transactions with Spring AOP. What is happening when the update1 method is called? (Select one)

A) There is only one transaction because the call to update2() is internal (it does not go through the proxy)
B) There is only one transaction because REQUIRES_NEW runs into the active transaction if one already exists
C) There are 2 transactions because REQUIRES_NEW always runs in a new transaction
