Class constants are accessed using the scope resolution operator :: with the class name, like ClassName::CONSTANT.

$obj->VERSION tries to access a property, not a constant; ClassName->VERSION is invalid syntax; $obj:VERSION uses single colon which is invalid syntax.

ClassName::VERSION -> Option A
