What are the disadvantages of Single$-$Uaser Contiguous Scheme? $($Choose all that apply$)$

It is not cost effective, as it serves the purpose of only one person at a time.

The jobs are allocated sequentially. Hence the requirement of operating system's work is more.

Does not support multi$-$programming

Only one job or program is loaded in to memory at any point of time

Even though there is a space to accommodate the waiting jobs, it is not possible accommodate more than one job.
