A for loop is the best choice when the exact number of iterations is known, in this case, the user entering exactly 20 values. A for loop allows the programmer to specify the number of iterations and ensures that the loop will run exactly 20 times. The other options, such as a do-while loop, sentinel controlled loop, or nested loop, do not guarantee that the loop will run exactly 20 times. An infinite loop should be avoided as it will continue to run forever, and the program will never complete.
