What does the following loop do?

int[] a = {6, 1, 9, 5, 12, 3};

int len = a. length;

int x = 0;

for (int i = 0; i < len; i++)

if (a[i] % 2 = = 0) x++;

System. out. println (x);

1. Sums the even elements in a.

2. Finds the largest value in a.

3. Counts the even elements in a.

4. Finds the smallest value in a

Option 3: Counts the even elements in a.

Explanation:

The for-loop will traverse through each of the number in array, a. Within the for-loop, each number is modulus with 2 to check if it is equal to zero. Any number modulus 2 that result in zero is an even number. Based on this condition, the x count value will be incremented by one whenever an even number is detected from the array.

At last, display the x count value after completion of the for-loop.
