Given the following code $($which is the same as in Q$1)$:

public class Person $\{$

private int age;

public Person$()\{$

age $=1$;

$\}$

public int getAge$()\{$

return age;

$\}$

public void getOlderByYears$($int years$)\{$

age $=$ age $+$ years;

years $=$ years $+1$;

$//$ POINT A

$\}$

$\}$

public class Main $\{$

public static void main$($String$[]$ args$)\{$

Person jean $=$ new Person$()$;

int ageAmount $=3$;

$//$POINT B

jean.getOlderByYears$($ageAmount$)$;

$//$POINT C

$\}$

$\}$

Part $1$

When we run the Java program above, what is the value of years at Point A$?$

$($a$)$

expression does not compile at Point A

$($b$)$

$3$

$($c$)$

$4$

$($d$)$

$0$

$($e$)$

$2$

$($f$)$

$1$

$0\%$

Part $2$

When we run the Java program above, what is the value of years at Point B$?$

$($a$)$

$3$

$($b$)$

$1$

$($c$)$

$2$

$($d$)$

$4$

$($e$)$

expression does not compile at Point B

$($f$)$

Part $3$

When we run the Java program above, what is the value of years at Point C$?$

$($a$)$

expression does not compile at Point C

$($b$)$

$0$

$($c$)$
