Consider a $4$ byte unsigned variable b$.$ Select all of the C expressions below that will evaluate to true if the bit at position $8$ is $1$ and will evaluate to false if the bit at position $8$ is $0.$

Recall:

In C$,$ any non$-$zero value evaluates as true.

We number bits starting with $0$ for the least significant bit, $1$ for the next least significant bit, etc.

$(($b & $0$x$100)/256)$

$(($b & $0$xfeff$)/256)$

$(($b $<<7)$ & $0$x$8$fff$)$

$(($b $*2)$ & $0$x$200)$

$(($b $<<7)$ & $0$x$8000)$

$(($b $/128)$ & $0$x$1)$
