A state might lose a congressional district due to a decrease in population, which can lead to that district being redrawn and potentially gerrymandered. Gerrymandering can impact minority rights by diluting the voting power of minority populations, as district lines may be redrawn to consolidate or spread out those voters in a way that diminishes their electoral influence. Therefore, the correct answer is:
• A decrease in population may cause a district to be redrawn and therefore gerrymandered.
