We have built a regression model that attempts to predict the height of an adult child based on both their mother's and father's heights. A friend of yours thinks it would be funny to try and predict the height of an adult child using a height of 10 feet tall for both the mother and the father. Which of the following terms is the name for the problem we would encounter if we were to do what your friend wants?
a) Autocorrelation
b) Extrapolation
c) Heteroscedasticity
d) Multicollinearity
