The cable, the ground, and the flagpole together form a right triangle with sides 26:24:10. You can find the missing length, 26, by squaring the two sides you know (which turn out to be legs), adding these two squares together (24^2 +10^2), and then finding the square root of the sum. This is the pythagorean theorem in action.
So the answer is choice C.
By the way, I found it the easy way...I know there's a special right triangle that everyone always uses, 5:12:13 (3:4:5 is also extremely popular) and so I could see that the sides you were given were just twice these lengths so...the missing side was twice the longest side or hypotenuse (2x13).

That sounds like the flagpole, the ground and the cable make a right triangle, so we can apply the Pythagorean Theorem. The cable is the diagonal, so its length is sqrt(10^2 + 24^2). 10^2 = 100, 24^2 = 576, so the cable's length is sqrt(676). The square root of 676 is 26, so that's the answer.
C.

Depends on where the cable is attached to the flagpole. What happens when we assume?
