Sometimes you just need to give a time and let your brain naturally work it out.

In this question the first letter of all the words are in alphabetical order with a letter skipped in between:.

C__, E__, G__, K__.

C, E, G, ___, K.

C(D), E(F), G(H), ___ , K.


C__, E__, G__, K__.

The logic method is very easy to understand. But in other ways is very complicated to learn if you are not very dedicated. Thanks for more explained to us.

c=3,e=5,g=7,k=11 here diff is 2

So, the middle lettere off g and k is i=9.
The next two same letters here m=13, o=15, q=17 here diff also 2 then here 19=s
So, ans is ISS.

It is clear and easy, only the first letter changes alternatively and the remaining letters are repeated.
