As ABC is inscribed in a semi circle, ABC is a right angle triangle. Angle ADB is 120, any perpendicular line from D to line AB bisects AB and let us assume the point of bisection is E. Now AED is 30, 60, 90 triangle. Given that AE is 3, AD will be 2*root 3. As triangle BDC is an equilateral, BC is also 2*root 3.
So the area of ABC is 1/2*6*2*root 3= 6*root 3, Hence answer is B
