question 3

Multiple Choice

Which of the following statements is false?

• A) Thread synchronization is necessary only for shared mutable data, i.e., data that may change during its lifetime.
• B) With shared immutable data that will not change, it's not possible for a thread to see old or incorrect values as a result of another thread's manipulation of that data.
• C) When you share immutable data across threads, declare the corresponding data fields XE "Keywords: final" XE "final:keyword" final to indicate that the values of the variables will not change after they're initialized. This prevents accidental modification of the shared data, which could compromise thread safety.
