Consider the following C$++$ classes:

class a $\{$

public:

void p$1()$;

virtual void p$2()$;

protected:

void r$1()$;

void r$2()$;

private:

void v$1()$;

$\}$;

class b : public a $\{$

public:

void p$1()$;

void p$2()$;

$\}$;

int main$()$

$\{$

b $*$x $=$ new b$()$;

x$->$p$1()$;

$(($a$*)$ x$)->$p$2()$;

return $1$;

$\}$

Does class b inherit the function v$1()?$

$[$ Select $]$

Does class b inherit the functions r$1()$ and r$2()?$

$[$ Select $]$

In main$(),$ which version of p$1()$ is called?

$[$ Select $]$

In main$(),$ which version of p$2()$ is called?

$[$ Select $]$
