Step 1  Given situation is that income elasticity of consumption is different for males and females while controlling for age, education level and marital status.  Step 2  The correct option is c. An interaction term of income with dummy variable representing gender status.  Because, the gender variables include two categories male and female. So, this category convert into 1 and 0 format which called as dummy variable technique. A dummy variable is a numerical representation of the categories of a nominal or ordinal variable. Hence, there is interaction term of income with dummy variable representing gender status.
