Which of the following statements is correct about the C#.NET code snippet given below? enum color : byte { red = 500, green = 1000, blue = 1500 }

• byte values cannot be assigned to enum elements.
• enum elements should always take successive values.
• Since 500, 1000, 1500 exceed the valid range of byte compiler will report an error.
• enum must always be of int type.
• enum elements should be declared as private.
