What is the simplified expression for the following Kmap?

$\backslash$table$[[$YZ$,],[$WX$,00,01,11,10],[00,1,1,1,1],[01,1,1,0,0],[11,0,0,0,0],[10,0,0,0,1],[,,,,]]$

$W^{\text{'}}{Y}^{\text{'}}+W^{\text{'}}{x}^{\text{'}}$

$x^{\text{'}}{Y}^{\text{'}}+Z^{\text{'}}{x}^{\text{'}}+x{Y}^{\text{'}}Z$

$W^{\text{'}}{Y}^{\text{'}}+W^{\text{'}}{x}^{\text{'}}+x^{\text{'}}Y{Z}^{\text{'}}$

$W^{\text{'}}x{Y}^{\text{'}}+W^{\text{'}}{x}^{\text{'}}+x^{\text{'}}YZ$
