Answer: (C)

Verified step by step guidance

1. Understand the concept of aseptic technique: Aseptic technique refers to a set of practices used to prevent contamination by unwanted microorganisms during laboratory procedures.
2. Recognize the importance of preventing contamination: Contamination can lead to inaccurate experimental results by introducing foreign bacteria or other microorganisms into the culture.
3. Identify the goal of aseptic technique: The primary goal is to maintain the purity of bacterial cultures, ensuring that only the intended bacteria are present for study.
4. Consider the impact on experimental results: Contaminated cultures can lead to erroneous data, affecting the reliability and validity of the experiment.
5. Acknowledge the role of aseptic technique in scientific research: By preventing contamination, aseptic technique helps ensure that experimental findings are accurate and reproducible, which is crucial for scientific progress.
