Answer 2

Hey mate!!!

$<b >Here is your answer ;</b >$

$<b > option ( ii ) is the incorrect answer. </b >$

$<b >Justification ;</b >$

We know that by pythagoras theorem, $a^2 + b^2 = c^2$, where, a, b < c.

=>$a^2 + b^2 - c^2 = 0$

Then,
i ) $9^2 + 40^2 - 41^2 = 0$

ii) $60^2 + 80^2 - 90^2 = 1900$

iii) $5^2 + 12^2 - 13^2 = 0$

iv) $7^2 + 24^2 - 25^2 = 0$.

Thus, you can find that only option (ii) is different from the rest, I hope you get it.
