Arrays and structures are __________ entities in that they remain the same size throughout program execution.

Which of the following statements is false?

a) Prior to C# 6, you could use a fully braced collection initializer to initialize a Dictionary’s key–value pairs. For example, if you had a Dictionary named toolInventory, you could create and initialize it as follows: ``` var toolInventory = new Dictionary{ {"Hammer", 13}, {"Saw", 17}, {"Screwdriver", 7} }; ``` b) The code in a) is shorthand for creating the Dictionary then using its Add method to add each key–value pair. c) C# 6’s index initializers enable you to clearly indicate the key and the value in each key–value pair as follows: ``` var toolInventory = new Dictionary{ ["Hammer"] = 13, ["Saw"] = 17, ["Screwdriver"] = 7 }; ``` d) Prior to C# 6, any collection that defined an Add extension method could be initialized with a collection initializer. As of C# 6, the compiler also supports collection initializers for any collection that has an Add instance method.
