Recall that at a high level, categories of inter-process communication (IPC) facilities include those that share memory and those that transfer data. Which of the following statements are correct about IPC facilities? A. Facilities that use data transfer, such as FIFO, can only be used between a parent process and a child process.
B. Facilities that share memory require more care in synchronizing data sharing.
C. Facilities that share memory can communicate a lot faster.

Facilities that share memory require more care in synchronizing data sharing (B) and facilities that share memory can communicate a lot faster ( C )

Explanation:

The true statements about IPC facilities are : Facilities that share memory require more care in synchronizing data sharing  and facilities that share memory can communicate a lot faster.   this is because facilities that require the sharing of memory between themselves require more care in the synchronization of data and  also copying of messages is prohibited which in turn makes it faster for the facilities to communicate a lot faster.
