HELLO DEAR,

 \frac{  \frac{1}{x}  }{ \frac{1}{x}  +  \frac{1}{y} }   +  \frac{ \frac{1}{x} }{ \frac{1}{x}  -  \frac{1}{y} }  \\  \\   =  >  \frac{ \frac{1}{x} }{ \frac{x + y}{xy} }  +  \frac{ \frac{1}{x} }{ \frac{y - x}{xy} }  \\  \\  =  >  \frac{xy}{x(x + y)}  +  \frac{xy}{x(y - x)}  \\  \\  =  >  \frac{y(y - x) + y(x + y)}{(x + y)(y -x)}  \\  \\  =  >  \frac{y(y - x + x + y)}{(x + y)(y - x)}  \\  \\  =  >  \frac{2 {y}^{2} }{ {y}^{2} -  {x}^{2}  }


hence, option (d) is correct


I HOPE ITS HELP YOU DEAR,
THANKS
