Let $Ebe$ the semiellipsoid and $Hbe$ the hemisphere into which $E$ will $be$ transformed. What equations will transform $E$ into a hemisphere?

$A.x=ax,y=by,$ and $z=cz$

$B.x=a{x}^2,y=b{y}^2,$ and $z=c{z}^2$

$C.x=\frac{a}{x},y=\frac{b}{y},$ and $z=\frac{c}{z}$

$D.x=a^{2}x,y=b^{2}y,$ and $z=c^{2}z$
