In Linux Operating System, when ___________is invoked, it is passed a set of…

Answer: clone() — the Linux kernel call that accepts flags to control resource sharing between parent and child.

Why clone() is correct:

• clone() accepts flags (for example CLONE_VM, CLONE_FILES, CLONE_FS, CLONE_SIGHAND, CLONE_THREAD) that determine which resources are shared or copied between the parent and child.

• By combining these flags, the caller can create a full separate process or create a thread-like entity that shares memory, file descriptors, or other attributes.

Why the other choices are incorrect:

• fork() duplicates the calling process to create a child with its own separate memory and resources; it does not take the clone-style flags to selectively share resources.

• pthread() is not a standard POSIX function name. The POSIX threads API uses functions such as pthread_create at the library level; these are not kernel calls that take clone-like sharing flags.

• thread() is not a standard Linux or POSIX system call name for creating processes or threads and is therefore not the correct kernel interface that accepts sharing flags.

Summary: use clone() when you need fine-grained control over what the child shares with the parent; fork() creates a separate process without those flags, and pthread/thread names refer to higher-level or nonstandard interfaces.
