Java Deserialization: Which Input Stream is Used?

The correct answer is 'C ObjectInputStream'.

In Java, deserialization is the process of converting a serialized representation of an object (typically stored in a file or transmitted over a network) back into an object in memory. This is achieved using the ObjectInputStream class.

Here's a breakdown of why the other options are incorrect:

• FileWriter: Used for writing text data to files, not for deserialization.
• FileReader: Used for reading text data from files, not for deserialization.
• ObjectOutputStream: Used for serializing objects into a byte stream, not for deserialization.
