Correlation indicates a linear relationship between two variables, meaning as one variable changes, the other variable tends to change in a specific direction (either positively or negatively) at a consistent rate. However, correlation does not imply causation (D), nor does it specify the nature of the relationship beyond linearity, such as being quadratic (B) or the direction of the relationship (C).
