A certain computer has two identical processors that are able to run in parallel. Each processor can run only one process at a time, and each process must be executed on a single processor. The following list indicates the amount of time it takes to execute each of four processes on a single processors:

• Process A takes 10 seconds to execute on either processor.
• Process B takes 15 seconds to execute on either processor.
• Process C takes 20 seconds to execute on either processor.
• Process D takes 25 seconds to execute on either processor.

Which of the following parallel computing solutions would minimize the amount of time it takes to execute all four processes?

1. Correct Answer
