Consider the following class definitions:

class A:

def $\_$init $($self$,$ par $=2$ :

pirint $("\frac{?}{\text{b}\text{a}\text{r}}(A),$ end $="")$

print $($par$)$ if par $13$ not None else print $(2)$

par $=2$

class $B(A)$ :

def $\_$Init $($self$,$ par$)$ :

$y=A($par$)$

What will be happen when the following statement is executed:

obj $=B(4)$

The code will print $"$B A $4"$
