How can I use 2 other classes on a base class. I have a class name subject ad it will contain the list of student class, subject name and teacher class

What I have tried:

I created student and teacher class that inherits from a person class now my problem is is storing student and teacher class on subject class.

  public class Student : Person
    {
        public Student(string FirstName, string LastName, string Gender) 
            : base(FirstName, LastName, Gender)
        {
            Console.WriteLine(FirstName, LastName, Gender);
        }
    }
}

public class Teacher : Person
    {
        public Teacher(string FirstName, string LastName, string Gender)
            : base(FirstName, LastName, Gender)
        {
            Console.WriteLine(FirstName, LastName, Gender);
        }
    }
}
