Observational or descriptive science concentrates on gathering information and describing what is observed in the natural world without manipulating the system. This approach involves collecting data, recording measurements, noting appearances or behaviors, and mapping patterns and distributions as they occur. It provides the descriptive foundation—seeing what exists and how things relate—which then can inspire questions, hypotheses, or experimental tests later on. That’s why this option fits the idea of scientific work based on information gathering best.

The other concepts are broader or more active in testing ideas: a theory is a well-supported explanation that integrates many observations; hypothesis-driven science centers on formulating testable predictions and testing them through experiments or controlled studies; the scientific method refers to the overall process of inquiry, which can include both observational data collection and experimental testing.
