Explanation:

Let’s look at the sequence:

J _ M K L J J _ K L J J _ K L _ J P _ L

Let’s break it down:

- We notice "J", then a blank, then "M K L".

- After the second blank, again we see "K L".

- Next, after the third blank, again "K L".

- The pattern looks like clusters of "J J K L" with some missing letters.

- The blanks seem to break the clusters. Let’s fill the blanks one by one.

Now, the options:

Option 1: J N O J K

Option 2: J N J K O

Option 3: N J K J O

Option 4: N J J O K

Now, let’s try Option 1 in the series.

J (J) M K L J J (N) K L J J (O) K L (J) J P (K) L

- Now, check pairings: After every "J J", you have some letter, then "K L" repeats–but not consistently.

- But notice: Sometimes the pattern is disturbed. Option 1 doesn’t really line up with anything consistent when you fill it in.

Let’s test Option 4: N J J O K

J (N) M K L J J (J) K L J J (O) K L (J) J P (K) L

- Now, check how “J J (J) K L” forms. We get "J J J K L", which fits a repeating cluster seen in the sequence.

- Similarly, "J J (O) K L", "J J (J) P K L"

- This option fits a repeating cycle in the series: “N J J O K” lines up best.

So the correct answer is:

Option 4: N J J O K

Here's how the options work:

- Option 1: Throws off cluster patterns; breaks the rhythm.

- Option 2 & 3: Also break the repeated clusters; letters don’t flow as in the sequence.

- Option 4: Follows the “J J (letter) K L” pattern, keeping the clusters intact and matching the cues hinted by the series.

So, Option 4 is the clear fit.
