Find the correct alternative that when filled in the blanks in the same sequence willmake the series logically complete.

_ D G C E _ J F H J _ I K M P _ N P S _​

Given: _ D G C E _ J F H J _ I K M P _ N P S _

Now, we check each options.

Option (a): CGNLP (Not Follow)

C D / G C / E G / J F / H J / N I / K M / P L / N P / S P

Option (b): CHNKP (Not Follow)​

C D / G C / E H / J F / H J / N I / K M / P K / N P / S P

Option (c): BHMKO (Not Follow)​

B D / G C / E H / J F / H J / M I / K M / P K / N P / S O

Option (d): BGMLO (Follow)​

B D / G C / E G / J F / H J / M I / K M / P L / N P / S O

So, the following pattern is: + 2 and - 4 alternately

Thus, correct option is (d).
