I think it's A and D as the network_administrators group would need to be part of "wheel" to perform sudo tasks... C is not valid as you're trying to eliminate the need for the password in the first place!

people who are saying A, how do you add members to a group via visudo? I understand A and D are the only answers that make sense but am still to know how to add members to a group via that sudoers file

The relevant admins are already members of the 'network_administrators' group, you're not adding them to a group using visudo, you're adding their already established group to the file.

visudo /etc/sudoers and then you need to add that line somewhere in the file: network_administrators ALL=(ALL) NOPASSWD: ALL

A and D are correct, once you add the group to the wheel group, you use the ALL directive which applies to the wheel group, allowing users to run ALL commands defined there, it should already be in the file, just commented out.
