C Correct answer
Explanation

The array intArr initially contains {22, 11, 66, 99}. After calling Arrays.sort(intArr), it becomes sorted: {11, 22, 66, 99}. Searching for 67 using Arrays.binarySearch yields an insertion point of index 3 (between 66 and 99). The return value is key insertion point index negated minus 1, which calculates to -(3) - 1 = -4.
