Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → JKMKJ
In a letter series with blanks, look for a block of letters that repeats; the blanks are then the letters the block needs at those places. The 16 places split into four blocks of four, each H J K M.
Block 1: H _ _ M needs J, K
Block 2: H J K _ needs M
Block 3: H J _ M needs K
Block 4: H _ K M needs J
The series is HJKM HJKM HJKM HJKM, and the blanks in order are JKMKJ.
