What was the name of the plan that called for a majority of white males in each state to take the oath of loyalty and denied the right to vote or hold office to any southerners who fought for the Confederacy

The correct answer is the Wade-Davis Bill.

The Wade-Davis bill was a proposed alternative to Abraham Lincoln's 10-Percent Plan. The Wade-Davis Bill required that a majority of white males in states that seceded to pledge their loyalty and had strict restrictions on office holding.
