Using the 2016 GSS, We Regressed the Number of Hours

Using the 2016 GSS, we regressed the number of hours of television watched on the average day on three variables: years of education, age, and marital status. Marital status is a dummy variable with 1 = married. We get the following results for the standardized regression coefficients: TVhours = - .20Educ + .07Age - .07Married. According to this equation,

A) none of the variables is significantly related to television viewing.
B) all three variables are significantly related to television viewing.
C) age has the strongest association with television viewing.
D) education has a stronger association with television viewing than age.
