Analyze the geometric patterns and select the option that logically follows.

The sequence shows a progression involving a square and a triangle.

1. □Δ: A square and a triangle are placed side-by-side. Both are in their standard, upright orientation.
2. □Δ: The triangle moves partially inside the square, creating an overlapping shape. Both shapes remain in their standard, upright orientation.
3. □Δ: The combined overlapping shape (square with triangle inside) is rotated or tilted.
4. □: The triangle disappears, leaving only the square. The square is in its standard, upright orientation.
5. □: The square is rotated or tilted.

• Presence of the triangle: The triangle is present in symbols 1, 2, and 3. It is absent in symbols 4 and 5. This suggests a pattern where the triangle disappears after the third symbol. Therefore, the next symbol (6th in the sequence) should not contain a triangle.
• Orientation/Rotation: The orientation of the shapes follows a pattern:
  • Symbol 1: Standard
  • Symbol 2: Standard
  • Symbol 3: Tilted
  • Symbol 4: Standard
  • Symbol 5: Tilted This pattern is "Standard, Standard, Tilted, Standard, Tilted". Following this, the next symbol should be in a Standard orientation.

Based on the patterns identified:

• The triangle should be absent.
• The remaining shape (the square) should be in its standard, upright orientation.

The options are presented in the bottom row of the image:

• Option A: A square, tilted to the right. (Incorrect orientation)
• Option B: A square, in standard, upright orientation. (Matches prediction)
• Option C: A triangle. (Incorrect shape, triangle should be absent)
• Option D: A square and a triangle, separate. (Incorrect shape, triangle should be absent)
• Option E: A square, tilted to the left. (Incorrect orientation)

The only option that matches both criteria (no triangle and standard orientation for the square) is option B.

The final answer is $\text{B}$
