We’ll go for LOGICAL because there is a simple logic behind the question.

All the angles together make up a circle, which equals 360 degrees: $$24x = 360$$. Since we are looking for 120 degrees, we can divide the equation by 3 and arrive at $$8x = 120$$. There aren’t any adjacent angles that can be added to up to create 8, except the angle $$8x$$ itself. So the largest number of adjacent angles is 1.
