The answer should be D: Zero.
A triangle has three sides. Two of them are called the legs and the last longest one is called the hypotenuse. You have to do this equation:
l^2 + L^2 = h^2
The sum of the legs to the power of 2 should equal the hypotenuse to the power of 2
7(7) + 2(2) = 10(10)
49 + 4 = 100. This is false. So you cannot make a triangle with these three side lengths.

Well, if you say it's A...  But that does make sense.  Using the triangle inequality theorem, there is only one triangle you can make from that.
