Explanation:

- The given series that needs completion is: _ V J R W B _ _ R W B V L _ _ B V _ _ W.

- Observing the patterns:

- “_ V J R W B” seems to suggest that the next sequence could use these letters again or use similar sequences.

- After “_ _ R W B V L”, it looks like it is repeating elements.

- Consistent elements throughout the sequence are "R W B V".

- Analyzing the options:

- Option 1: B V K R W M R

- Possible fill: BVJRW B V K RWB V L K B V M W.

- Option 2: A V K R W M R

- Possible fill: AVJRW B A K RWB V L K B V M W.

- Option 3: A W K R X N R

- Elements "X" and "N" do not match the sequence pattern.

- Option 4: B W K R W M R

- Possible fill: BWJRW B W K RWB V L K B V M W.

- Matching option with pattern:

- The repeating pattern "R W B V" is found in both Options 1 and 4.

Therefore, option 1 (B V K R W M R) is correct.
