Select the combination of letters that when sequentially placed in the blanks of the given series will complete the series.k _ d q _ c _ m _ q y _ k m _ q _ c

Let's count the total number of elements including blanks:There are 18 positions in total. Let's try dividing the series into groups of 6 letters:k _ d q _ c | _ m _ q y _ | k m _ q _ cComparing the first group and the third group:k _ d q _ c vs k m _ q _ cThis suggests:The second letter is m.The third letter is d.The fifth letter is y (from the middle group _ m _ q y _).Let's check the repeating pattern as k m d q y c:Group 1: k m d q y c (Blanks filled: m, y)Group 2: k m d q y c (Blanks filled: k, d, c)Group 3: k m d q y c (Blanks filled: d, y)Let's list the filled letters in sequence:m, y, k, d, c, d, yThis matches Option C: m y k d c d y
