Study the given pattern carefully and select the option that can replace the question mark (?) in it.

​

Given: 

Logic: We take blank square; dark square; blank triangle; dark circle

In first figure $$\rightarrow$$ 3 blank square; 1 dark square; 3 blank triangle; 2 dark circle

In second figure $$\rightarrow$$ ​1 blank square; 3 dark square; 2 blank triangle; 3 dark circle​

Similarly,

For, ? $$\rightarrow$$ 2 blank square; 2 dark square; 3 blank triangle; 2 dark circle

The code of ? is 2; 2; 3; 2

Thus, correct option is (b).
