C Correct answer
Explanation

R/3 uses semaphores for interprocess communication (IPC) to synchronize access to shared resources among different processes. Message queues and named pipes are not primary IPC mechanisms used by R/3. Task memory is not an IPC mechanism at all - it's internal process memory. Semaphores are the Unix/Linux IPC mechanism that R/3 leverages.
