Explanation:

Statement I:
Divisibility rule of 11: The difference between the sum of even places and the sum of odd places is 0 or that number is divisible by 11.
Difference = Sum of odd place – Sum of even place = (1+4+1+0+7)-(0+2+3+1+7) = 13 – 13 = 0, it is divisible by 11.
Statement II:
173 is square of approximately 13. So, below 13,
prime numbers are -> 2, 3, 5, 7, 11
Now, 173 is not divisible by 2, 3, 5, 7 and 11. So, it is a prime number.
So, both the statements I and II are correct.
