Answer: A

Explanation:

Assertion (A): The String class in Java is immutable.
- True. In Java, once a String object is created, it cannot be changed. Any modification to a String object results in the creation of a new String object.
Reason (R): Immutable objects cannot be modified once they are created, and any operation on a String object results in the creation of a new String object.
- True. This is a correct explanation of immutability. Since String objects are immutable, any operation that appears to modify a String actually creates a new String object.

a) Both Assertion(A) and Reason(R) are true and Reason(R) is correct explanation of Assertion(A).
