String objects are immutable, meaning that once they are created, their value cannot be modified. Any operation that appears to modify the value of a string object actually results in creating a new string object. StringBuilder objects, on the other hand, are mutable. This means that their value can be modified without creating a new object. Hence, the correct choice is (B) immutable, mutable.
