: Consider the C program: #include int$*$ f $($int choice, int x$)\{$ int y $=$ x; if $($choice $==0)\{$ return &x; $\}$ else $\{$ return &y; $\}\}$ void main $($int argc, char$**$ argv$)\{$ int a $=5$; int b $=10$; int $*$p $=$ f $(0,$ a$)$; int $*$q $=$ f $(1,$ b$)$; printf $("\%$d

$",*$p$)$; printf $("\%$d

$",*$q$)$; $\}$ Consider the following statements: $1.$ The contents of local variable p is a pointer to a heap$-$allocated object. $2.$ The contents of local variable q is a dangling pointer. $3.$ The calls to printf result in this program having $$undefined behavior.$$ Identify all of the statements that are true: A : $1$ and $3$ B : $1$ and $2$ and $3$ C : $2$ D : $1$ and $2$ E : $2$ and $3$ Question $2$: Recall that in C
