$f$:$\{0,1{\}}^4\{0,1{\}}^4$ and $f(x)$ is obtained by replacing the first bit of $x$ with $1.$ For example, $f(0100)=1100g$:$\{0,1{\}}^4\{0,1{\}}^4$ and $g(x)$ is obtained by removing the first bit of $x$ and placing the bit at the end. For example, $g(1000)=0001.$

Select the correct value for $(f$@$g)(0011).$

$1111$

$1110$

$0111$
