Link to msmpi.lib
Call MPI_Start
Call MPI_Comm_rank
Call MPI_Finalize
B. Include mpi.h
Link to msmpi.lib
Call MPI_Init
Call MPI_Comm_rank
Call MPI_Finalize
C. Include mpi.h
Link to ccpapi.tlb
Call MPI_Init
Call MPI_Comm_rank
D. Include mpi.h
Link to msmpi.lib
Call MPI_Init
Call MPI_Comm_size
Correct Answer: B
