Answer:
The correct option is A) assembling a large number of samples for comparison.
Explanation:
A specimen can be described as a sample of anything which is used for scientific or biological researches. For example, a sample of blood withdrawn from a person to perform various tests.
Specimens can be collected and stored and they help scientists by comparing the results of different treatments which they apply to the specimens. Hence, option A is correct.
Other options like Option C are not correct because a specimen has nothing to do with making expensive instruments reliable.
