What type of software is provided with the expectation that the users will change it to meet their particular needs? (Points: 5)

Commercial Software
Open Source Software
Public Domain Software
Shareware

is it "Open source software" im confused

I'd say open source.

The other software can be used and upgraded as available, but you cannot change the programs.

Open source software provides the source code as well, so you can go in and make changes, rebuild the programs, and they will then work differently.
