A series of steps followed to solve problems.

• A. Water Bath
• B. Regenerative Medicine
• C. Scientific Method
• D. Erlenmeyer Flask

Answer: (C)

The idea being tested is recognizing a structured approach scientists use to investigate questions and solve problems: the scientific method. This process involves a logical sequence—observing or asking a question, forming a testable hypothesis, designing and conducting controlled experiments, collecting and analyzing data, drawing conclusions, and communicating results. It’s about solving problems through evidence, repeatability, and careful reasoning, not just using a tool or describing a field. A water bath is simply equipment to keep samples at a constant temperature, not a sequence of steps. Regenerative medicine is a field focused on repairing or replacing damaged tissues, not a problem-solving process. An Erlenmeyer flask is glassware used for mixing or storing liquids, again not a procedural method. So the concept that best fits “a series of steps followed to solve problems” is the scientific method.
