In Tildernia, the number of reported paid family leave days taken by employed fathers after the birth of a child has declined 5 percent in the last three years. However, perhaps part of the decline is due to fathers using paid personal leave or vacation days to take time off following the birth of a child. After all, studies show that men who take paid family leave days are more frequently overlooked for promotion than those who do not use this benefit.

Which of the following, if true in Tildernia, most strongly supports the proposed explanation?

(A) In the last three years, there has been no increase in the total number of paid personal leave or vacation days used by employed men.
(B) When employees take family leave days after the birth of a child, they also receive a small increase in pay to assist in caring for that child.
(C)A continuing shift in social attitudes has led to an increase in the number of men who assume more responsibilities in the household.
(D) Employers who encourage fathers to take paid family leave after the birth of a child do not in general have lower benefit costs than employers who do not encourage fathers to do so.
(E) In the last three years, the average number of births per household has gradually increased.
