In an operating system, which of the following statements defines the best-fit allocation algorithm? Search the entire list of available memory and allocate the first block that is big enough.Search the entire list of available memory and allocate the smallest block that is big enough.Search the entire list of available memory and allocate the largest block.Search the entire list of available memory and allocate a random block.

The first-fit, Best-fit and the Worst-fit algorithm can be used fora.Contiguous allocation of memoryb.All of thesec.Indexed allocation of memoryd.Linked allocation of memory

Given memory partitions of 100 KB, 500 KB, 200 KB, 300 KB and600 KB (in order), how would each of the first-fit, best-fit and worst-fit algorithms place processes of 212 KB, 417 KB, 112 KB and 426KB (in that order) ? Which algorithm makes the most efficient use ofmemory?

Explain the best fit, first fit and worst fit algorithm.
