Here angle ACB = 180 -120 = 60 degree

Now angle ABC = 180 - (60+60) = 60 degree

Therefore$$\triangle$$ABC = equilateral triangle and all sides are equal.

Hence option C

Angle ACB is 180-120 = 60°. Sides length is proportional to angle measures meaning that the longest side corresponds to the largest angle.

Now, since angle ACB and BAC are equal, also the correspondent sides will be equal.

Then, AB = BC and answer is C!
