Show answer & explanation
Correct answer: B
Concept
In a seating puzzle, a clue of the form "X is between Y and Z" fixes X's two neighbours as exactly Y and Z, so chaining such clues links people into one continuous run. Further clues - an "opposite" (directly facing) pair, a "second to the left/right" position, and a gender or role fact - then pin down where the remaining people sit relative to that run, leaving exactly one arrangement consistent with every clue at once. Once the full arrangement is fixed, the number of people "between" two seats is simply the count of seats lying on the arc joining them.
Application
From "J is between L and F" and "G is between I and F", F's only two neighbours are J and G, so L, J, F, G, I form one unbroken run of five consecutive seats.
The remaining lady clue places the third lady member (besides E and H) at the seat already inside this run that sits between F and I - fixing that seat as G's.
The opposite-seat clue (F directly facing E) and the second-to-the-left clue (H two seats to the left of J) together fix the last three seats - E, H and K - completing the one arrangement shown in the diagram below.
Cross-check
Reading every seat that lies on the arc from K to F in the completed diagram gives three people seated between them, matching the keyed value.
Therefore, three persons are seated between K and F.
