A certain binary communication system that uses Nyquist criterion pulses, a received pulse has samples $x_n=\{0\mathrm{.}0,0\mathrm{.}1,1,0,-0\mathrm{.}2,0\mathrm{.}1\}.$ A three$-$tap zero$-$forcing equalizer with coefficients $[C_{-1},C_0,C_1{]}^{TT}$ is designed to give a proper Nyuist pulse. The tap$-$coefficient $C_{-1}$ is

$($A$)-0\mathrm{.}096$

$($B$)-0\mathrm{.}2$

$($C$)0\mathrm{.}2$

$($D$)0\mathrm{.}96$
