Read the three annotations of a paragraph. Which is likely the best way to annotate the paragraph?

A. The 2013 Supreme Court decision (Shelby County v. Holder) gutted the Voting Rights Act of 1965. The Voting Rights Act said that states with a history of discrimination needed to get preclearance for any new voting laws. It had a formula establishing which states these were. Before Shelby, 9 states had to get such preclearance. After Shelby, with preclearance no longer necessary, hundreds of measures making voting more difficult were adopted by those states and others. For example, laws making it easier to vote were overturned, and laws requiring photo identification for voting were passed.

B. The 2013 Supreme Court decision Shelby County v. Holder gutted the Voting Rights Act of 1965. The Voting Rights Act said that states with a history of discrimination needed to get preclearance for any new voting laws. It had a formula establishing which states these were. The Shelby decision invalidated this formula. Before Shelby, 9 states had to get such preclearance. After Shelby, with preclearance no longer necessary, hundreds of measures making voting more difficult were adopted by those states and others. For example, laws making it easier to vote were overturned, and laws requiring photo identification for voting were passed.

C. Shelby County v. Holder (2013) gutted Voting Rights Act by getting rid of formula for which states needed preclearance. Effect of Shelby: new state laws making voting more difficult.
