\(x^w=1\): \(x\) can be any value with \(w\) as \(0\) and \(x\) \(1\) can take \(w\) any value. Not sufficient \(\Large{\color{red}\chi}\)

\(w\) even nothing from it \(\Large{\color{red}\chi}\)

Combined

\(w =0\) can give different values for \(x\), so not sufficient. \(\Large{\color{red}\chi}\)

Therefore E
