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.

Suppose that a metamorphic virus, DoomShift, is 99% useless bytes and 1% useful bytes. Unfortunately, DoomShift has infected the login program on your Unix system and increased its size from 54K bytes to 1,054K bytes; hence, 1,000K bytes of the login program now consists of the DoomShift virus. Barb has a cleanup program, DoomSweep, that is able to prune away the useless bytes of the DoomShift virus, so that in any infected file it will consist of 98% useless bytes and 2% useful bytes.

If you apply DoomSweep to the infected login program, what will be its new size?
