Dropping a predictor from the regression equation could either result in a decreased correlation or the same correlation as before. If the predictor was not significantly contributing to the regression equation, then dropping it may not change the correlation drastically. However, if the predictor was a strong contributor to the regression equation, dropping it could result in a decreased correlation. Therefore, both options B and C are possible outcomes.
