Step-by-step explanation:
The type of testing in which potential users try out a program and provide feedback is User acceptance testing (option c).User acceptance testing (UAT) is a crucial step in the software development process.
It involves testing the system with real users to determine if it meets their needs and expectations. In UAT, users perform various real-world scenarios and provide feedback on the functionality, usability, and overall satisfaction of the program.
For example, in the development of a new mobile app, potential users would be invited to test the app on different devices and operating systems. They would then provide feedback on issues encountered, user interface design, and any other aspects that can be improved.
