Answer:

c. The variable is not a useful predictor of the dependent variable

Explanation:

In multiple regression, a small p-value (usually < 0.05) is desired. A low p-value indicates that the coefficient is statistically significant and that the variable is a meaningful addition to your model because changes in the predictor’s value are related to changes in the dependent variable. If the p-value is large, then it indicates that the variable is not useful as a predictor for the dependent variable since it is not statistically significant.
