Answer:  D - Obtuse Triangle

An obtuse triangle is a triangle in which one of the angles is an obtuse angle. (Obviously, only a single angle in a triangle can be obtuse or it wouldn't be atriangle.) 

An obtuse scalene triangle. All sides are unequal, the longest side is longer than it would be if it were the hypotenuse of a right triangle. The obtuse angle opposite the longest side could be computed by cosine law.

According to Behera: Here 10²+6²=136 ie less than 169 ie 13²,
here a²+b²<c²=> the ∆ is obtuse angled ∆.
