A researcher is considering the following variables as determinants to the variable earnings (Earn): Variable DFemme is a binary variable that takes the value 1 if the individual is a female, and 0 otherwise; Variable DMale is a binary variable that takes on the value 1 if the individual is male, and is 0 otherwise; Variable DMarried is a binary variable that takes on the value 1 for married individuals and is 0 otherwise; Variable DSingle is is a binary variable that takes on the value 1 for unmarried individuals and is 0 otherwise; Variable X is a control variable that has continuous values. The researcher would like to regress logarithmic weekly earnings (Earn) on these explanatory variables. Select ALL models below that do NOT suffer perfect multicollinearity:
