Each user can connect with 4 other users in the network. Therefore, the total number of potential network connections can be calculated using the combination formula:
nCr = n! / r! (n-r)!

In this case, the number of users (n) is 5, and the number of connections to be made (r) is 2.

So, 5C2 = 5! / (2! × (5-2)!) = 10.

However, we must also consider that each connection can be made in two directions (user A can connect with user B, and user B can connect with user A). Therefore, the total number of potential network connections is 10 × 2 = 20.

Hence, the correct answer is C) 20.
