The question asks to identify which two of the four drawings (A, B, C, D) are the same as the object on the left (object X). To solve this:

• The object X on the left has a specific 3D structure consisting of several cubes in a zigzag formation, with two vertical and two horizontal segments.

• Now, let's analyze each option:

  • A looks very similar to X but rotated. It has the same number of cubes and the same orientation for the segments.
  • B has a different structure; the bottom part of B doesn't match the bottom part of X, so B is not the same.
  • C also matches the same number of cubes and orientation as X, suggesting it's the same object but viewed from a different angle.
  • D has the same general form as X, but its structure is slightly different, especially in how the cubes are aligned.

Thus, A and C represent the same object as X but viewed from different angles.

The correct answer is A and C.
