The Idea That a Large National Debt Is "Mortgaging the Future

The idea that a large national debt is "mortgaging the future of our children and grandchildren" is misleading because:

A) it is the Federal Reserve that will be responsible for making interest payments on the debt.
B) future generations will have to bear the opportunity costs of the resources that are used today.
C) future generations will not be liable for the interest obligations of the national debt.
D) future generations will inherit the interest income as well as the interest obligations.
