Final answer:
The correct option is C). The species of an organism can be most accurately determined from a strand of hair due to distinctive microscopic characteristics that differ among species.
Step-by-step explanation:
Of the options provided, C) Species can most accurately be determined from a strand of hair. When scientists examine a hair sample under a microscope, they look at patterns, structures, and other microscopic characteristics that are specific to different species. This helps in forensic studies and wildlife biology where identifying the species is crucial. For example, the hair of a rabbit can be distinguished from the hair of other animals due to unique characteristics that are found in rabbit evolutionary history.
