Answer 4

-Create a modal class
-Include all the required properties
-Pass this class name to the required collection
For ex:
class Person
{
public int Age {get; set;}
public string Name {get; set;}
public double Weight {get; set;}
public char Gender {get; set;}
}

List<Person> personList = new List<Person>();

Now, the collection of different datatypes is under single collection called "personList"
