In \Delta ABC  AB = 6 \sqrt 3  cm, AC = 12 cm and BC = 6 cm.

AB^2+BC^2=108+36

                           =144

                           =12^2

                           =AC^2 

It satisfies the pythagoras theorem.

Hence, ABC is a right angled triangle and right angled at B.

Option C is correct.
