    Given this method in a class: public String toString() { StringBuffer buffer = new StringBuffer(); buffer.append(‟ buffer.append(this.name); buffer.append(‟>‟); return buffer.toString(); } Which is true?() A: This code is NOT thread-safe. B: The programmer can replace StringBuffer with StringBuilder with no other changes. C: This code will perform well and converting the code to use StringBuilder will not enhance the performance. D: This code will perform poorly. For better performance, the code should be rewritten: return “”;
