Which statement allows you to properly check the char variable code to determine whether it is equal to a $C$ and then output This is a check?

if $($ code $==\text{'}$ C$\text{'})$

cout $$ "This is a check $\frac{?}{?}$

$"$;

if $($ code $==C)$

cout $$ "This is a check" $$ endl;

if $($ code $="$C$")$

cout $$ "This is a check

$"$;

if code is equal to C

cout $$ "This is a check $\frac{?}{?}$

$"$;
