Problem Analysis:

The task involves identifying a pattern or rule in a 3x3 grid of squares and determining the missing square in the bottom-right corner. Each square contains a 3x3 grid with black and white cells. The goal is to choose the correct option (A, B, C, or D) that fits the established pattern.

Step-by-Step Solution:

#### 1. Observing the Grid:
The grid is divided into three rows and three columns. We need to identify any patterns horizontally, vertically, or diagonally.

#### 2. Horizontal Patterns:
- Row 1:
- First square: Top-left corner is black.
- Second square: Bottom-right corner is black.
- Third square: Bottom-left corner is black.
- Pattern: The black cell moves clockwise around the outer edge of the grid.

- Row 2:
- First square: Entire left column is black.
- Second square: Entire middle row is black.
- Third square: Entire right column is black.
- Pattern: The black area moves from left to right across the grid.

- Row 3:
- First square: Top-left 2x2 block is black.
- Second square: Bottom-middle 2x2 block is black.
- Third square: ? (We need to determine this based on the pattern).

#### 3. Vertical Patterns:
- Column 1:
- First square: Top-left corner is black.
- Second square: Entire left column is black.
- Third square: Top-left 2x2 block is black.
- Pattern: The black area expands downward and outward.

- Column 2:
- First square: Bottom-right corner is black.
- Second square: Entire middle row is black.
- Third square: Bottom-middle 2x2 block is black.
- Pattern: The black area expands upward and inward.

- Column 3:
- First square: Bottom-left corner is black.
- Second square: Entire right column is black.
- Third square: ? (We need to determine this based on the pattern).

#### 4. Diagonal Patterns:
- Main Diagonal (Top-left to Bottom-right):
- First square: Top-left corner is black.
- Second square: Middle cell is black.
- Third square: Bottom-right 2x2 block is black.
- Pattern: The black area expands diagonally.

- Anti-diagonal (Top-right to Bottom-left):
- First square: Bottom-right corner is black.
- Second square: Middle cell is black.
- Third square: Top-left 2x2 block is black.
- Pattern: The black area expands anti-diagonally.

#### 5. Determining the Missing Square:
From the horizontal pattern in Row 3:
- The black area in the first square is in the top-left 2x2 block.
- The black area in the second square is in the bottom-middle 2x2 block.
- Following the clockwise movement observed in Row 1, the next logical position for the black area would be in the bottom-right 2x2 block.

From the vertical pattern in Column 3:
- The black area in the first square is in the bottom-left corner.
- The black area in the second square is in the entire right column.
- Following the expansion pattern, the next logical position for the black area would be in the bottom-right 2x2 block.

#### 6. Matching the Options:
- Option A: Matches the pattern of having the bottom-right 2x2 block filled with black.
- Option B: Does not match any observed pattern.
- Option C: Does not match any observed pattern.
- Option D: Does not match any observed pattern.

Final Answer:

The correct answer is A.

\boxed{A}
