A system has two users bobby and rosie as per the output below. If we configured the file $/$etc$/$sudoers to allow rosie to execute a binary file $/$home$/$bobby$/$mybin$/$sometask as bobby, what would be the effective UID of the process?

ubuntu@ubuntu: $ tail $-2\frac{?}{et}\frac{c}{p}$asswd

bobby:$x$:$1002$:$1004$:$,,,\frac{\text{:}}{h}om\frac{e}{b}$obby$\frac{\text{:}}{b}i\frac{n}{b}$ash

rosie:$x$:$1003$:$1003$:$,,,\frac{\text{:}}{h}om\frac{e}{r}$osie$\frac{\text{:}}{b}i\frac{n}{b}$ash

$$ a$.0$

b$.1003$

c$.1004$

d$.1002$
