C) testScores[2][2]

Explanation:

Consider that the above has been translated into a java program. A two dimentional array is declared to hold the value of the testScores.

The complete program and the output is given below

public class twoDimenTestScores {

public static void main (String[] args) {

int[][] testScores = {

{80, 82, 90, 87, 85},

{79, 80, 74, 82, 81},

{93, 95, 89, 100, 85},

{60, 72, 65, 71, 79}

};

System. out. println (testScores[3][1]); / / prints 72

System. out. println (testScores[0][4]); / / prints 85

System. out. println (testScores[2][2]); / / prints 89

System. out. println (testScores[1][3]); / / prints 82

}

}
