If <ABC would be 90, 6^2 + 8^2 would be equal to 10 = AC.
But here AC is more than 10 that is 10.5
So, <ABC is greater than 90 degree.
Ans: A

Simply use the 3:4:5 right triangle rule.
We see it should have been 6:8:10 but we have 10.5 ; that means hypotenuse is stretched further making angle greater than 90.
Hence A
