Explanation:

Let’s break down the clues:

- Three people buy items between A and D. That means there are three people sandwiched between them.

- Two people buy between B and A. So B/A can't be at the first or last place.

- A buys right before G and also after C. Which means the order is … C, A, G…

- Two buy between H and C.

- A buys after B (so, B comes before C, A, and G).

- F buys before E.

- Neither F nor E is at the first or last position.

Let’s try to fit this puzzle together, focusing on C:

- Since A is after B and right after C, we get B … C, A, G.

- With three between A and D, and two between B and A, the only way it works is if C is near the beginning.

- When you put it together: B, H, C, A, G, F, E, D is a possible order.

- Now count how many are after C: after C, you have A, G, F, E, D. 

So, five people buy after C.

Let’s match with the options:

- Option:1, None

- Option:2, Two

- Option:3, Three

- Option:4, Four

- Option:5, Five    ??

In summary, five people buy after C. Would be happy to walk you through the exact sequence if you want the positions for everyone, but you nailed it.
