A Correct answer
Explanation

In Java, the trim() method returns a canonical string from the string pool if the resulting string is a literal. However, because trim() creates a new string object, == usually compares references. In many JVM implementations, this specific literal comparison might return true, but equals() is the proper way to compare content.
