Why? Please, Can anyone explain it?

It's star network. Mesh requires n(n-1) /2.

Here, it is asked for a number of ports not physical channels. So, n-1 is the correct answer.

If suppose, N number of devices are connected with each other in a mesh topology, the total number of ports that is required by each device is N-1. Assume there are 5 devices connected to each other, hence a total number of ports required is 4.
If suppose, N number of devices are connected with each other in a mesh topology, then a total number of dedicated links required to connect them is NC2 i.e. N (N-1) /2.
In Figure 1, there are 5 devices connected to each other, hence a total number of links required is 5*4/2 = 10.
