Two networks each provide reliable connection-oriented service. One of them offers a reliable byte stream and the other offers a reliable message stream. A process writes 1024 bytes, then

• A. both networks will receive 2048 bytes as a single unit
• B. message stream network will receive 1024 bytes only at one time. But byte stream network will receive 2048 bytes as a single unit.
• C. message stream network receives 2048 bytes as a whole. But bytes stream 1024 bytes only at a time.
• D. both will receive 1024 bytes at one time since there is a gap between writes
