Answer: A

Explanation:

Pairwise testing is a test design technique that reduces the number of test cases needed to cover all possible combinations of input parameters, by testing only pairs of parameters at a time. It is based on the assumption that most defects are caused by interactions of at most two factors. Pairwise testing is suitable for testing systems that have multiple parameters with discrete values, such as browsers, plug-ins, servers, and operating systems. It can help to find defects that are related to the compatibility and interoperability of the system in different environments.
