Explanation:

Please find the complete question in the attachment file.

In this question except for choice c, all are incorrect which can be defined as follows:

• It is inappropriate because when Dfemme and Dmale are paired together, it will core product multicollinearity.
• It's inaccurate because the sum of Dmarried and Dsingle equals 1 but produces ideal multicollinearity.
• It's also inaccurate since Dmarried and Dsingle, as well as Dfemme and Dmale, will all add up to one.
