In 2010, north carolina was covered by section of the voting rights act of 1965, which required states that had a history of electoral discrimination against minorities have their electoral maps approved (or precleared) by either a federal court or the department of justice.

The answer is section 4

Explanation:

The voting rights act was issued in order to end racial discrimination in the state. This allowed a number of black americans to be registered to vote, even in case of having a low level of english proficiency. North Carolina used english proficiency tests to determine who could register to vote. Under section 4 of the voting rights act, the rights to vote were expanded to include all black americans.
