Answer 1

Answer: B. Reliability

Explanation: Reliability is the act of establishing the degree of accuracy or dependency of the outcome or output of a measurement, calculation or experiment. Establishing the reliability of an experiment is aimed at expunging doubt in an experiment or measurement. Reliability of an experiment can be established by repetitive performance of the experiment to determine if it yields the same result or almost similar result which is consistent, reproducible and reliable.
