Question: What is the significance of using the volatile keyword with a variable in Java?

A) It guarantees that changes to the variable are immediately visible to all threads and prevents threads from caching the variable.
B) It ensures that the variable can only be modified by a single thread at a time, providing thread safety for write operations.
C) It allows the variable to be stored in a non-volatile memory, improving access speed for frequently accessed values.
D) It enables the variable to be automatically initialized when an instance of the class is created.
