Assuming the sound wave frequency of an audio signal ranges from $35Hz$ through to $15KHz.$ if we digitize this audio using the following digital audio formats, which of the below format$($s$)$ will not cause the sound to lose part of its original pitch?

a$.15KHz,16$ bits, stereo

b$.35KHz,8-$bit, mono

Sps $2Wps$

spg $=2**$ up

c$.44\mathrm{.}1Hz,16-$bit, stereo

Sps $30KHz$

$sps=2415k=30k$

Anything bigger than $30$ will keep

d$.$ all answers are false the original pitch unharmed
