Answer: Precise measurements are important for Scientific Accuracy in order to get correct results
Explanation:
Precision is how close the Agreement is between repeated measurements under the same conditions. For example, if a measured value 36.7cm has three digits, or significant figures. Significant figures indicate the precision of a measuring tool that was used to measure a value
Accuracy is how close a measurement is to the correct value for that measurement.
When taking scientific measurements it is very important to be both precise and accurate. Bad equipment, human error can give inaccurate results.

The Chondrichthyes is a class that comprises the cartilaginous fishes such as batoids, ratfish, sharks and others, The Chondrichthyes and the Osteichthyes also known as bony fish were distinguished in early classification but it was not clear at that time when bony skeletons appeared in the vertebrates.
Traces of bone tissues that are found in fossil and living Chondrichthyes are suggested that these cartilaginous fishes derived after the origin of the bony skeleton in vertebrates.
Thus, the correct answer is option C.
