Question

From the given options, select the group of letters that, when inserted in order from left to right into the blanks of the incomplete series, will logically complete it. S KBFHBSFKSF B

1. A. FHSKBHHK
2. B. FHSKHKHK
3. C. FHSKHBHK (Correct answer)
4. D. FHSHKBHK

Correct Answer

Option C — FHSKHBHK

Detailed Solution & Explanation

The correct answer is FHSKHBHK.

Key Points

• The series repeats the five-letter block S F H K B. Written in groups of five:
  • S _ _ K B | _ F H _ B | S F _ K _ | S F _ _ B
• Filling each gap from the block pattern:
  • block 1 needs F, H; block 2 needs S, K; block 3 needs H, B; block 4 needs H, K
• Reading the gaps left to right gives F, H, S, K, H, B, H, K = FHSKHBHK.

Additional Information

• With 20 letters and a 5-letter block, the series is exactly four repetitions — checking that the total length divides by the block length confirms the reading before any filling.
• Longer blocks are what make Tier II series harder than Tier I; five- and six-letter blocks are common here.
• Write the block above the series and align them column by column, so each blank can be read off directly rather than counted.
• All four options contain the same letters in different orders, so the sequence is what is being tested — filling correctly but transcribing out of order still scores zero.
