The following program generates an error. Why? finalintNUM_ELEMENTS=5; int[] userVals = new int[NUM_ELEMENTS]; int i; userVals[0] = 1; userVals[1] = 7; userVals[2] = 4; for (i = 0; i <= userVals.length; ++i) { System.out.println(userVals[i]); } a. Variable i is never initialized. b. The array userVals has 5 elements, but only 3 have values assigned. c. The integer NUM_ELEMENTS is declared as a constant d. The for loop tries to access an index that is out of the array's valid range. JAVA
