To solve this question, we need to identify the pattern or rule that is being followed in the given series.
Let's analyze the given series:
JAK, KBL, LCM, MDN, _____
If we look at the first letters of each term, we can see that they follow the pattern: J, K, L, M, ...
If we look at the second letters of each term, we can see that they follow the pattern: A, B, C, D, ...
If we look at the third letters of each term, we can see that they follow the pattern: K, L, M, N, ...
Based on this pattern, we can deduce that the next term should have the first letter as "N", the second letter as the next letter in the alphabetical order (which is "E" after "D"), and the third letter as the next letter in the alphabetical order (which is "O" after "N").
Therefore, the next term in the series is "NEO".
The correct answer is option B) NEO.
