To increase the popularity of the chemical analysis section, a \"One Question per Day\" campaign has been launched; this aims to foster active technical exchanges while also providing financial rewards to users. 【Daily Question】 (Single-choice question) Standard materials are required to have uniform material composition, ( ), be produced in batches, possess accurate values, and come with standard material certificates. A. High relative molecular mass B. Stable performance C. Stable output D. Meeting quality standards. Answer: B. Post your answer in the replies to participate; you will receive +2 wealth points for that. If you answer all questions correctly, you’ll get an additional +3 to +8 wealth points. Those who provide thorough analyses and explanations for the questions or answers, or include detailed calculation processes, will receive extra wealth rewards. If your answer is correct and your analysis/explanation is accurate, it will be marked as the best reply (or the best assistance). Feel free to answer the questions.
