1. object,var,dynamic can store any type of value.object and dynamic no need to initilize at the time of declaration but var should be initilize at the time of declaration.

dynamic is not type safe because compiler does not have any information about type.
var is type safe beacuse compiler have all information about stored value.
3. object and dynamic can be passed as method arguments and also a method can return object ,dynamic type.
but var can't be pass as method arguments and also no method can return var type.
