The Decision of the Constitution's Framers to Allow Federal Judges

The decision of the Constitution's framers to allow federal judges, all unelected, to serve lifetime appointments demonstrated their concern with:

A) reflecting the ideas of French political theorist Montesquieu about balances of power.
B) giving the court enough independence to practice judicial review, as explicitly given the courts in the Constitution.
C) making sure that justice would be free from all political influence and bolstered as judges grew wiser and more experienced over time.
D) the excesses of democracy, as well as concern for guarding against political interference from other branches.
