Which of the following is an advantage of parallel implementation?
A) The process is inexpensive and thus can be undertaken over a long period of time.
B) The process makes both systems process the same case, and if the new one operates well, the output is the same.
C) The existing process is automatically switched off when new processes are running, which limits redundancy.
D) The implementation makes each system process distinctly different cases.

Parallel implementation involves running both the existing and the new system simultaneously, processing the same cases. This allows for direct comparison of the output from both systems, which helps ensure that the new system operates well and produces the same output as the existing system. This is an advantage because it reduces the risk of errors and discrepancies in the output. The other options (A, C, and D) are not characteristics of parallel implementation or are incorrect.
