The question asks for the WRONG statement about SPLATT. Options A and B describe true facts about SPLATT (it has projects under SPIAcceptanceTests.sln for each LOB, and uses XML scripts in Visual Studio 2005). Option C says 'SPLATT can be used for Mainframe testing' - if this is FALSE (making it the wrong statement), then SPLATT cannot be used for mainframe testing, which is plausible if SPLATT is specifically for distributed systems testing. Option D 'All of the above' cannot be correct if we're looking for a single wrong statement.
