Concept:Use the clues to fix the possible division strengths, place people in each division, and reject the cases that violate the conditions.Explanation:There are 9 people and 3 divisions, each having a different strength between 2 and 4. So the possible division strengths are $2$, $3$ and $4$.$N$ and $P$ are in the same division, but not in Production. So they are either in Design or Sales.$R$ is in Production, and $L$ is not in Design and does not work with $P$.Consider Case 1: $N,P$ in Design and $L$ in Sales. Then $J$ cannot be with $L$ or with $N,P$, so $J$ goes to Production. But $K$ cannot be in Sales or Design, and placing $K$ in Production would give $J$ two co-workers. So Case 1 is impossible.Consider Case 1a: $N,P$ in Design and $L$ in Production. Then $J$ must be in Sales with exactly one co-worker, and $K$ joins $J$ in Sales.Now $Q$ works with $O$ and is not in Design. Since Sales already has $J,K$, putting $Q,O$ in Sales would give $J$ more than one co-worker, so $Q,O$ go to Production.The remaining person, $M$, goes to Design.Final arrangement:Design: $N, P, M$Sales: $J, K$Production: $R, L, O, Q$Here, Sales has 2 members, which is less than Design having 3 members, so the condition is satisfied.Answer:$P$ works with $N$ and $M$. Hence, among the given options, the correct answer is $M$, i.e., Option B.
