Explanation:

• Chipped or cracked glassware can cause injuries (cuts) and lead to inaccurate experimental results (e.g., leakage of chemicals). So it's not okay to use.
• Returning unused chemicals to original containers can contaminate the entire stock (e.g., if a chemical picked up impurities during the experiment).
• For an incomplete lab experiment, the instructor has the knowledge and authority to guide on the next steps (e.g., if it's safe to resume, if there's an alternative approach).

Answer:

• "Chipped or cracked glassware is okay to use": B. False
• "Return all unused chemicals to their original containers": B. False
• "If a lab experiment is not completed, you should": discuss the issue with your instructor (as per the selected option in the image).
