One of the major differences between a scanning electron microscope and a transmission electron microscope is:

a. SEM gives a three-dimensional image while the TEM gives a two-dimensional image.

b. TEM gives a three-dimensional image while the SEM gives a two-dimensional image.

c. TEM gives a color image while the SEM is in black and white.

d. SEM gives a color image while the TEM is in black and white.
