Question

which of the following boxes should replace the question mark (?) to complete the pattern?

Explanation:

Step1: Observe column - wise pattern

In each column, the number of shapes in the first row is 2, in the second row is 3, and in the third row is 4. Also, the shapes are the same within a column. The first - column shapes are triangles, the second - column shapes are circles, and the third - column shapes are squares.

Step2: Determine the missing shape

Since the missing box is in the first column which has triangles, and it should have 3 triangles to follow the row - wise number pattern.

Answer:

B. Three triangles
