Which of the following statements is valid about advantages of generics?

For the code snippet given below, which of the following statements are valid?

public class MyContainer<T> where T: class, IComparable
{
//Insert code here
}

1 Class MyContainer requires that it's type argument must implement IComparable interface.

2 Compiler will report an error for this block of code.

3 There are multiple constraints on type argument to MyContainer class.

4 Class MyContainer requires that its type argument must be a reference type and it must implement IComparable interface.

For the code snippet given below, which of the following statements are valid?

public class MyContainer<T> where T: IComparabte
{
// Insert code here
}

1 Class MyContainer requires that it's type argument must implement IComparabte interface.

2 Type argument of class MyContainer must be IComparabte.

3 Compiler will report an error for this block of code.

4 This requirement on type argument is called as constraint.
