_________ is when the sequence of instruction is guaranteed to execute as a group, or not execute at all, having no visible effect on system state.
A) Critical section
B) Mutual exclusion
C) Atomic operation
D) Starvation

Question

The description perfectly fits the definition of an atomic operation. Atomic operations are indivisible, meaning they will either execute completely or not execute at all, ensuring that the system state remains consistent. Critical sections refer to a block of code that must be executed by only one process at a time, while mutual exclusion is a technique used to ensure that only one process can access a shared resource at a time. Starvation occurs when a process is perpetually denied access to a shared resource. None of these fully match the given description of an instruction sequence executing as a group with no visible effect on the system state.
