The correct option is B 10
As per the given pattern, the first figure has 2 pink blocks.
The second figure has 4 pink blocks and third figure has 6 blocks.
∴ The pattern follows:
For each figure, the blocks increase by 2.
In the fourth figure number of pink blocks = 6 + 2 = 8 blocks
In the fifth figure, number of pimk blocks = 8 + 2 = 10 blocks
Thus, the fifth figure in the given pattern will have 10 blocks.
