Suppose a program utilizing a $4-$way set associative cache accesses a $1-$byte word located at the address $0$x$071$A$.$ In this cache, the Index column stores the set index for each group of $4$ lines, and the Bytes column numbers the bytes from left $($byte $0)$ to right $($byte $3).$ The V column holds the valid bit for each line.

$($a$)$ Describe the Address format using $1$ bit per box, specifying the function of each bit in the box below it$,$ where CT denotes a tag bit, CI represents an Index bit, and CO signifies an Offset bit.

$($b$)$ Identify the cache entry that is accessed and the cache byte that is returned $($in hexadecimal$).$ Also, indicate whether a cache miss occurs.
