Option C correctly implements the required logic. It checks if the current value of the index is less than the length of the array AND if the current value is not equal to X. If both conditions are true, it increments the index. Once X is found in the array, the method returns the index. If X is not found, the method returns the length of the array, which is one more than the last index in the array. Therefore, this implementation satisfies the requirements of the method.
