Final answer:
QC analysis of microbiological media is important to avoid false positives or negatives, ensuring accurate and reliable testing results. The option (B) is correct.
Step-by-step explanation:
QC analysis of microbiological media in the laboratory is important to avoid false positives or negatives. Ensuring that the media used is properly formulated and free from contamination, reduces the chances of getting incorrect results due to contamination.
For example, contaminated media could lead to the growth of bacteria that are not present in the original sample, giving a false positive result. Additionally, QC analysis helps maintain the accuracy and reliability of the testing process, which is important for the proper identification and disposition of finished products. Therefore, option (B) is correct.
