Explanation:

Let’s break it down, step by step. Here’s what we know:

- There are three departments: Marketing, Production, Operations.

- At least 2 people in each department, no more than 4 in any one.

- B and E work in the same department.

- H and G work in the same department, but not with A or M.

- J, K, and L work in the same department.

- M is in Operations.

- B isn’t in Marketing.

- A is in Production, but not with L.

Let’s map it out:

1. J, K, L are together. That’s a trio.

2. B and E are a pair somewhere (but not in Marketing).

3. H and G are together, but not with A and not with M.

4. M is alone (so far) in Operations.

5. A is in Production, but not with L.

So—let’s slot in J, K, L. If J, K, L are a group of three, they can’t be in Production with A, since A can’t be with L. So, J, K, L are together elsewhere—likely Marketing (since B and E aren’t in Marketing).

B and E can’t be in Marketing. If H and G can’t be with A or M, then they must pair up in one department. Since there must be at least 2 per department, let’s lay it out:

- Marketing: J, K, L (3 people)

- Production: A, H, G (but wait, H and G can’t be with A), so this can't be. Or A, B, E?

- But B and E aren't in Marketing, so perhaps B, E in Production? But they could also be with another person to make it at least 2 per department.

Let’s take it in:

Department assignments:

- Marketing: J, K, L

- Production: A, B, E (since B and E are together, and B isn't in Marketing)

- Operations: M, H, G (since H and G can't be with A or M; but only way to do this is with M, H, G together)

So now:

- Marketing: J, K, L

- Production: A, B, E

- Operations: M, H, G

Now, who is in a different department compared to the others in the options?

- Option 1: M (Operations)

- Option 2: K (Marketing)

- Option 3: L (Marketing)

- Option 4: J (Marketing)

- Option 5: E (Production)

So K, L, J are all together in Marketing. E is in Production. M is in Operations.

M is the only one listed who works in a different department compared to all the rest.

Here’s what this really means:

- Among the options, M is the only one who is not grouped with K, L, J (all in Marketing) or E (who is with A and B in Production).

- So, the correct answer is:

- Option: 1, M
