[Reveal] Spoiler:
Is this question asking me if I can figure out if xyz = 1? Or is it asking me if any of the two statements fit the condition for xyz to equal 1?
My answer was E, as none of the statements met the condition xyz = 1. But the answers in the book say it's B, as statement 2 gives a definitive NO answer.
Can someone please help me on what the correct approach is for these DS questions.
