Answer 2

Option(d) className:: functionName; is the right one.

• When the programmer defines the function with a special keyword static then the function became a static function.
• Unlike other functions, the access right for the static function is restricted.
• So the function declares static when the access is wanted restricted.
• When the static function is need to be called the scope resolution function is used.
• Therefore, the scope resolution operator '::' is used for access purposes.
