Correct answer: It is based on multiple observations.

Brief explanation: A scientific law is a concise description of a consistent pattern seen in nature, established by repeated observations and experiments. Newton’s first law (the law of inertia) summarizes the observed behavior of bodies when no net force acts on them — a conclusion built from many observations and experiments (e.g., Galileo’s studies of motion on inclined planes, subsequent laboratory tests), not from a single test or no evidence. It’s not a “theory” in the sense of explaining why inertia exists; rather it’s an empirical generalization.
