Explanation:

Let’s break this down step by step:

- The years given are: 1946, 1958, 1963, 1971, 1994, 2006.

- Sum of M + Black’s ages is 86: 2019 minus birth years should add to 86.

- Sum of J + Yellow’s ages is 81: Again, difference from 2019 adds to 81.

- N likes Orange and is born in an odd year. So N is 1946, 1963, or 1971.

- The one who likes Pink was born in an even year and is older than Black.

- M does not like Red or Pink.

- O is younger than the one who likes Orange.

- K is older than Pink.

- L does not like yellow.

Let’s do the math:

- Ages in 2019: 2019 - years = 73, 61, 56, 48, 25, 13.

- Possible pairs for 86: 73+13, 61+25, 56+30, but 30 isn’t on the list. Only 73 (1946) + 13 (2006) = 86 fits.

- So, M and Black are 73 and 13 (either way).

- For 81: 73+8, 61+20, 56+25, 48+33, only 56+25 = 81 works.

- So, J and Yellow are 56 and 25 (either way).

Now, if O is younger than Orange, and Orange is N, who’s in an odd year (1946/1963/1971). The youngest odd year is 1971 (48y). Younger options: 25 (1994), 13 (2006), but 13 is already used.

So O must be either 25 or 13.

- If O is 13 (2006), only the one born in 2019 could be after him, but there is no such person.

- If O is 25 (1994), only the person born in 2006 is after, so only one person was born after O.

To answer the question: How many persons born after O?

- If O is born in 1994 (age 25 in 2019), only one person (the one born in 2006) is after O.

- So the answer is One.

- Option 4: One.

Here’s the answer in simple form:

Correct answer: Option:4–One.

There is only ONE person born after O. The person born in 2006. This fits all clues.
