Which of the following is true after executing this code? $($the line numbers are for your reference and have no meaning in the code$)$

Line $1$:$$ int var$1=500$;

Line $2$:$$ int var$2=1000$;

Line $3$:$$ int $*$ ptr$1=$ &var$1$;

Line $4$:$*$ptr$1=2000$;

Line $5$:$$ int $*$ ptr$2=$ ptr$1$;

Line $6$:$$ ptr$1=$ &var$2$;

ptr$1$ contains $2000$

Running the following code after Line $6$

$*$ptr$2=50$;

would put $50$ in ptr$2$

Running the following code after Line $6$

$*$ptr$2=50$;

would put $50$ in var$2$

Running the following code after Line $6$

$*$ptr$2=50$;

would put $50$ in var$1$

var$1$ contains $2000$

Running the following code after Line $6$

$*$ptr$1=10$;

would put $10$ in var$2$

Running the following code after Line $6$

$*$ptr$1=10$;

would put $10$ in var$1$

Running the following code after Line $6$

$*$ptr$2=50$;

would put $50$ in ptr$1$
