Option B is the answer, no doubt. The readObject method is the secret sauce that puts the object back together after it's been serialized.

The readObject method is like the opposite of the writeObject method. It's called after the object is brought back to life, not before.

Option B is the way to go. The readObject method is used to reconstruct the object after it's been deserialized.

Well, let's think about it. The readObject method is used to deserialize an object, so it makes sense for it to be called after the object is deserialized.
