Consider the following snippet of $C$ code. Assume the Oth element of arr is held at address $04000.$

uint${16}_t$ arr$[5]=\{3,1,4,0,5\}$;

uint${16}_{t}x=$arr;

uint${16}_{t}y={?}^{**}$arr;

uint${16}_{t}z={?}^{**}(x+2)$

a$.$ What value is held in $x?$

b$.$ What value is held in y$?$

c$.$ What value is held in $z?$
