Show answer & explanation
Correct answer: C
A microkernel keeps only essential services in kernel mode and moves other services, such as file systems or device drivers, to user space. This reduces the size of the kernel, so statement (i) is true. The Mach operating system was developed at Carnegie Mellon University and is a classic example associated with the microkernel approach, so statement (ii) is also true.
