A group of scientists are working on research. All of them need to simultaneously work on the computer and perform different operations. Which operating system do they need to use?

A. single user/single tasking operating system

B. multiuser/multitasking operating system

C. single user/multi tasking operating system

D. real-time operating system

I think the answer is B Multiuser / multitasking

Multiuser / multitasking operating system (B)

Multitasking is taking up of more than one task at a time by a user. for all the scientist to work simultaneously on the computer and perform different operations at the same time, the operating system has to be designed as a multi user/multitasking operating system to enable this that

A group of scientists work basically on research and for a research to be successful you have to multitask and multi users will be involved to ensure its success.

MOST operating systems come with the multitasking and Multiuser interfaces to enable modern day challenges/tasks to be carried out on the systems.
