Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

BinaryFormatter and SOAPFormatter both require the [Serializable] attribute to serialize and deserialize objects. These formatters work with the full object graph and need the attribute to know which types can be safely serialized. XmlSerializer does NOT require [Serializable] - it only serializes public fields/properties and works differently, requiring parameterless constructors instead. This is why option A is correct and option D (which includes XmlSerializer) is incorrect.
