The square root of a number ends with '7' if the number itself ends with '9'. This is because 7*7 = 49.

Let's check the options:

a) 113569 - This number ends with '9', so it's possible that its square root ends with '7'.

b) 31567 - This number ends with '7', so its square root will not end with '7'.

c) 8281 - This number ends with '1', so its square root will not end with '7'.

d) 26813 - This number ends with '3', so its square root will not end with '7'.

So, the answer is option a) 113569.
