Find out the odd one. 
Let’s analyze the given options one by one:
- Option A: The shape inside the box in option A has a triangle and a circle, which is different from other shapes that involve a combination of different geometric shapes (square, triangle, and circle).
- Option B: The shapes in the box involve a circle, square, and triangle, and follow a similar pattern as the other options.
- Option C: Similarly, option C involves different shapes (circle, square, and triangle) in different orientations.
- Option D: This option is the most different as it involves a circle and square, with the other shapes (triangle) placed differently.
Thus, option A is the odd one out as it doesn't follow the same pattern of shapes as the others.
Final Answer: (D) A
