Q: Answer-Which of the following statements is true regarding user-level threads compared to kernel-level thre...

User-level threads are managed by a library in user space, and the kernel is unaware of them. If one thread makes a blocking system call, the kernel blocks the entire process, thus blocking all other threads within that process.

A User-level threads are generally slower to create and manage.

B If one user-level thread performs a blocking system call, the entire process may block.

C Kernel-level threads are managed by a thread library in user space.

D User-level threads can take advantage of multiple processors simultaneously without kernel support.

E Context switching between user-level threads requires a mode switch to kernel mode.
