Answer:
(B) multicollinearity is present.
Explanation:
Multicollinearity -
It is the process where , one of the predictor variable in the multiple regression model can be linearly predicted from the others with the substantial degree of accuracy , is known as multicollinearity or collinearity .
In this case , the coefficient estimated of the multiple regression can change erratically for even a small change in the model .
hence , from the question , the indication is of (B) multicollinearity is present .
