Find out the answer figure which completes the problem figure matrix.

Problem figure:

The correct answer is Option (1) → 

Observe the 3 × 3 matrix row-wise.

Row 1

• Circle with plus → combination of circle and plus
• Plus
• Circle

First figure = combination of the next two figures.

Row 2

• Triangle with dot
• Dot
• Triangle

Again, first figure = combination of the next two figures.

Row 3

• Angle (L-shape)
• Line
• ?

Following the same rule,
Angle (L) = combination of two lines (one vertical + one horizontal)

Since one line is already given in the middle box, the missing figure must be the other line, i.e. a vertical line.
