Answer:
b. Conceptual models help us see how things are related and how they connect or work together. This helps us develop a hypothesis based on changes in a variable and the corresponding response of another variable.
Step-by-step explanation:
A conceptual model refers to a vivid representation or conceptualization of the working of a system. Hence conceptual models offer explanations to ideas about systems.
They help to fit all the facts together so that one can make sense of a system. Also, it helps us to understand how changes in one variable affects the other in a system, thereby helping us to formulate a testable hypothesis.
