Answer must be C

  • Message Passing Interface (MPI) is a standardized and portable message-passing system
  •  it has become a de facto standard for communication among processes that model a parallel program running on a distributed memory system.
  • It can run on any hardare platform. It is Portable ,Efficient, Flexible
  • Communicator objects connect groups of processes in the MPI session. Each communicator gives each contained process an independent identifier and arranges its contained processes in an ordered topology.
  • MPI_Comm_Size returns the total number of MPI processes in specified communication

Please refer this nice article for more details
