Explanation:

Let’s break down what’s really going on here:

- There are 7 boxes stacked in a column: K, D, S, M, G, C, N.

- G is right at the top.

- N’s box sits three boxes above K. So, if K is at the bottom (position 7), N is at position 4. Label positions from 1 (top) to 7 (bottom) for clarity.

- C is just above N, so if N is 4th from the top, C must be at 3.

- D is right below S – so wherever S is, D is immediately below.

- One box sits between D and M – not touching, with one open gap.

Let’s sketch out what fits:

1. [G]

2. [ ]

3. [C]

4. [N]

5. [ ]

6. [ ]

7. [K]

K is at 7, N is at 4, and C is at 3. G is at 1.

Now, where do M, D, and S go? Let’s try placing S and D together as a pair:

If S is at 5, D is at 6. If M is one gap away, then M can only fit in slot 2 (since 3 and 4 are taken by C and N). Let's check:

1. G

2. M

3. C

4. N

5. S

6. D

7. K

There it is—the arrangement works.

Now, the question: How many boxes between M (2) and N (4)?

- Directly between them: position 3 (C), so just one box sits between M and N.

So, the right answer is:

Option 1: One

Here's how the options stack up:

- Option 1 (One): Correct—just C in between M and N

- Option 2 (Two): Not enough boxes

- Option 3 (Three): Doesn't fit

- Option 4 (Five): Too many

- Option 5 (None): Nope—there’s C in between

You can visualize the stack as G, M, C, N, S, D, K, and that middle slot, C, is the single box between M and N.
