Lets number A, B, C, ..., Z as 1, 2, 3, ..., 26 and again A, B, C, ..., Z as 27, 28, 29,..., 52 and so on.
Then A->C=2
C->F=3= 2+1
F->K=5=3+2
K->S=8=5+3
S->E=12=8+4
E->V=17=12+5
So, next is V+17+6 or V+23= S..... Option 3)

the diff between A and C is 1.
and the diff between C and F is 2
and the diff between F and K is 4
and the diff between K and S is 7
and the diff between S and E is 11(count as cyclic order)
and the diff between E and V is 16

it comes a sequence like 1,2,4,7,11,16 so next number is 22. From V we count 22 letter is Comes in S. so Ans is S

From the alphbetical order (cyclic order),
The position between each letter is 1,2,4,7,11,16.
i.e., No. of position bet a and c = b (only one letter)
Now, No. of position bet c and f = d and e (Two letters)
Succeeding like this the series become 1,2,4,7,11,16.
Now, the diff bet each no. is 1,2,3,4,5 and contiuous is 6.
so, add 6 with 16 we get, 22.
so, count 22 position after v we can get s.
Therefore the ans will be, "s".
