Spurious Correlation.

a. The correlation between X and Y is spurious

b. X is the cause of Y

The three conditions necessary for causation between variables are covariance (relationship between variables), temporal precedence (the cause must precede the effect in time), and elimination of plausible alternative explanations (other possible causes are ruled out).
