Computers and servers consist of a large number of components that are semiconductors. Why is it essential that these components be cooled to maintain optimal performance? A. Semiconductors have varying resistance depending on the temperature 

B
Semiconductors operate in high current circuits that would heat the room to uncomfortable lev els in a short amount of time

C
Semiconductors are always so small that any heat would quickly melt the wire attached to it 

D
It is not necessary to cool semiconductors they work well at all temperatures
