Which of the following general classes of computers designed for medical, engineering, or animation and graphics design uses are optimized for visualization and rendering of three-dimensional models, and typically have fast processors, large memory, and advanced video cards?
a) mainframes
b) supercomputers
c) workstations
d) servers
e) personal computers

Servers is the general classes of computers designed for medical, engineering, or animation and graphics design uses are optimized for visualization and rendering of three-dimensional models, and typically have fast processors, large memory, and advanced video cards.

D) servers

Explanation:

Better to use servers, where it can handle multiple tasks since it has enough multiple microprocessors.

Normal PC memory is little slow then server memory.  In case slow processing the graphics or animation end user can include memory cards in servers.  Good advanced video graphics card be insert to the server slot for better performance. Good advance video graphics has also extra memory to process the graphics animation.

Normally personal computers also be achieved but it has own limitation.  Simple animation can be achieved by personal computers.

i will say b. laboratory technician   and if wrong then sorry

he could use bold or bigger text just a suggestion.
