Question: In Java, what is the primary role of the transient keyword when applied to a field in a class?

A) It prevents the field from being included in the serialized form of the object, thus not being saved or restored during serialization.
B) It ensures that the field is initialized to a default value when an object of the class is created.
C) It makes the field thread-safe by preventing multiple threads from accessing it simultaneously.
D) It allows the field to be accessed only within the class where it is declared, regardless of its access modifier.
