Final answer:
The correct option for the method of process cooperation through sharing where processes are not explicitly aware of each other is Shared Memory, which allows processes to interact with the same memory space for efficient information sharing.
Step-by-step explanation:
The student's question relates to the mechanisms by which cooperation between processes occur in a computing system, particularly how processes can interact by sharing covers processes without explicit awareness of each other. When considering the provided options, B) Shared Memory is the correct answer. Shared Memory is a method where multiple processes access the same memory space; they read and write to a shared section of RAM without sending specific messages to communicate. This enables processes to cooperate and share information efficiently, but it requires careful synchronization to prevent conflicts. In contrast, Message Passing involves sending and receiving message packets between processes, Semaphores are used to control access to shared resources, and Mutexes (mutual exclusion objects) provide locking mechanisms to prevent simultaneous access to shared resources by multiple threads or processes.
