In this case both the flows can start without any error and requests can be received on both ports. Flow names
httpListener1 can call other flow using HTTP request without any issues.
Hence correct answer is
The mule application start successfully
Web client requests can be received at URI on port 2222 and on port 3333.
Lets check why other options are incorrect
1) The mule application fails to start. There is URL path conflict because both HTTP Listeners are configured with same path ---- This is incorrect as port value is different in both listeners
2) The mule application start successfully. Web client requests can only be received at URI on port 2222 but not on port 3333 --- This is incorrect as there is no reason for not receiving requests on port 3333
3) The mule application fails to start because of the port binding conflict as HTTP request also use same port i.e. 3333 --- Port binding conflict will not happen in this case. It would have if both listener configurations would have been on same port . But that is not the case here.
