Reference types are stored on stack and value types are stored on heap area.

Boxing allows you to convert value types to reference types.

For boxing, during runtime it creates a temporary reference type box for the object on the heap

Unboxing allows you to convert reference type to value type

In C#, we can define one and only one main( ) method .

If there is more than one main( ) method defined in your programme ,the compiler will return compile time error.

If there is more than one main( ) method defined you can explicitely tell the compiler which main( ) method is to be used as the entry point.

All the statements are wrong

These are the names that one user gives to variables such as the user defined types(eg;classes and structs)

These are not case sensitive.

Their names must begin with a letter or with a underscore .

They must not contain any numeric characters

You can not use C# keywords as the Identifiers

abstract is a valid identifier .

_Identifier and \u006fIdentifier are identical

Identifiers can also contain unicode characters.

Both are essential templates for which we can create objects.

Both structs and classes are reference types and are stored on heap .

For both struct and class, we use 'new' keyword to declare an instance.

All of the above are correct

Value types are stored in heap and reference types are stored in stack area.

Boxing allows users to convert value types to reference types

Unboxing allows users to convert value type to reference type.

During runtime boxing creates a temporary reference type box for the object on the heap.
