Can some one help me with this Visual basic question?

Which of the following general statements is true of property procedures?

(1)The developer calls the methods of a property procedure by calling the Get or Set statements.

(2) Property procedures are more restrictive than creating equivalent fields.

(3)To create a property that is write-only, use the WriteOnly keyword in the property procedure declaration.

(4)A read-write property should have a Get and Set block.
