B.
Tests designed by someone from a different department within the company; tests designed by the author; tests designed by someone from a different company.
C.

D.
Tests designed by someone from a different department within the company; tests designed by someone from a different company; tests designed by the author.
This option has someone nearer to the written code in each statement. All other options are not in this order.
Tester independence refers to the degree to which the tester is separate from the development team to avoid bias and increase the objectivity of the tests. The highest level of independence is achieved when tests are designed by someone from an entirely different company, followed by someone from a different department within the same company, and then by another member of the development team. The lowest level of independence is when tests are designed by the author of the code being tested.
