A Correct answer
Explanation

StringBuffer's equals() method compares object references (inherited from Object), not content. So sb2.equals(s1) returns false because they're different objects. String's equals() compares content, but it only returns true when comparing with another String, so s1.equals(sb2) returns false. Output is false,false. Option A is correct.
