ANSWER C

Best fit : The allocator places a process in the smallest block of unallocated memory in which it will fit.
Worst fit : The memory manager places a process in the largest block of unallocated memory available.
First fit : There may be many holes in the memory, so the operating system, to reduce the amount of time it spends analyzing the available spaces, begins at the start of primary memory and allocates memory from the first hole it encounters large enough to satisfy the request.
