From Pythagorean theorem:

a)

[tex]6^2+8^2=36+64=\boxed{100}\\\\10^2=\boxed{100}[/tex]

Right triangle.

b)

[tex]8^2+15^2=64+225=\boxed{289}\\\\17^2=\boxed{289}[/tex]

Right triangle.

c)

[tex]7^2+24^2=49+576=\boxed{625}\\\\26^2=\boxed{676}[/tex]

Not a right tiangle.

d)

[tex]5^2+12^2=25+144=\boxed{169}\\\\13^2=\boxed{169}[/tex]

Right triangle and correct answer is C - 7, 24, 26.
The answer is C, I think so
