What is the output of the following code?#include <iostream>using namespace std;int main() { int a[] = {5,1,15,20,25}; int i, j, k; i = ++a[1]; j = a[1]++; k = a[i++]; cout << i << " " << j << " " << k; return 0;}Options: Pick one correct answer from below3 2 152 3 202 1 151 2 20

The correct answer is 3 2 15.

Here's the step-by-step explanation:

1. The array a is initialized with the values {5,1,15,20,25}.

2. i = ++a[1]; This line first increments the value at a[1] (which is initially 1) by 1, making it 2. Then, it assigns this value to i. So, i is now 2 and a[1] is also 2.

3. j = a[1]++; This line first assigns the value at a[1] (which is now 2) to j, and then increments a[1] by 1. So, j is now 2 and a[1] is 3.

4. k = a[i++]; This line first assigns the value at a[i] (which is a[2] and is 15) to k, and then increments i by 1. So, k is now 15 and i is 3.

5. cout << i << " " << j << " " << k; This line prints the values of i, j, and k, which are 3, 2, and 15 respectively.
