Q $29(4$ pts$)$ in Fig $1,$ assuming the program starts executing in MAIN and then calls F$2,$ which then calls F$1$ which then calls F$3$ that then calls F$4.$ Using STATIC Scoping, what variable are $$ALIVE$$ if in F$4?$

f$)\{$Global :$($X and A and B$),$ F$1$:W$,$ F$4$:B$\}$

g$)\{$Global :$($X and A and B$),$ MAIN:X$,$ F$2($A and B$),$F$1$:W$,$ F$3$: A$,$ F$4$:B$\}$

h$)\{$Global :A $,$ MAIN: X$,$ F$1$:W$,$ F$4$:B$\}$

i$)\{$Global :$($X and A$),$ F$1$:W$,$ F$4$:B$\}$

j$)$ Can$$t tell by looking at fig $1.$
