Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.

BOARD, BOARW, BOAIW, ?, BLZIW, YLZIW

BOZIW

Explanation:

BOARD, BOARW, BOAIW, ?, BLZIW, YLZIW

The logic followed here is :

B → (0) → B → (0) → B → (0) → B → (0) → B → (-3) → Y

O → (0) → O → (0) → O → (0) → O → (-3) → L → (0) → L

A → (0) → A → (0) → A → (-1) → Z → (0) → Z → (0) → Z

R → (0) → R → (-9) → I → (0) → I → (0) → I → (0) → I

D → (-7) → W→ (0) → W → (0) → W → (0) → W → (0) → W

So, the letter-cluster that replaces the (?) to complete the series is "BOZIW"
