Answer:
d. All of the above
Explanation:
A microspectrophotometer is an instrument used to measure the spectra of microscopic samples, thus, it is used for color comparison between samples.
It is able to measure very small samples , as small as 1 x 1 micrometers. That is, smaller than the diameter of a human hair, therefore it is suitable for the analysis of many other types of fibers that can be mounted on microscope slides.
The microspectrophotometer allows to acquire extremely small sample spectra without destroying them at all
