Question

Identify the figure that completes the pattern of the question figure.

• A. a
• B. b
• C. c
• D. d

Hint:

In non-verbal reasoning pattern problems, always check two things: (1) whether all elements of a set (shapes) are present, and (2) whether the shading/filling alternates consistently. This avoids confusion between similar-looking options.

Answer 1

The Correct Option is A

Step 1: Observe the grid structure. 
The figure is arranged in a $4 \times 4$ block pattern (four $2 \times 2$ groups). Each block contains four different shapes: - Circle, - Square, - Triangle, - Diamond. Thus, every $2 \times 2$ block contains all four shapes without repetition. 

Step 2: Shading rule. 
Notice the alternation of filled and outline patterns: - In the top-left block: Circle (filled), Square (outline), etc. - In the other blocks: Shading alternates systematically so that within a $2 \times 2$ block, two shapes are filled and two are outlines. 

Step 3: Identify missing block. 
The missing bottom-right $2 \times 2$ block must: 1. Contain all four shapes (circle, square, triangle, diamond). 2. Follow the filling/outline alternation (two filled, two outlines). Checking the answer options: - (a) Contains Circle (outline), Triangle (filled), Square (filled), Diamond (outline) → matches both shape-completeness and shading balance. - (b), (c), (d) either repeat shading wrongly or mismatch the placement of shapes. 

Step 4: Confirm the match. 
Thus, the correct block is option (a) because it completes the last $2 \times 2$ block with all four shapes in proper shading order. \[ \boxed{\text{Option (a)}} \]
