Given the code fragment:
static void addContent () throws Exception {
Path path = Paths.get("D:\\company\\report.txt");
UserPrincipal owner = path.getFileSystem().getUserPrincipalLookupService().lookupPrincipalByName("Bob");
Files.setOwner(path, owner);
// insert code here - Line **
br.write("this is a text message ");
}
System.out.println("success");
}
Assume that the report.txt file exists.
Which try statement, when inserted at line **, enables appending the file content without writing the metadata to the underlying disk?

• A.  try (BufferWriter br = Files.newBufferedWriter (path, Charset.forName ("UTF - 8"), new
  openOption [] {StandardOpenOption.APPEND, StandardOpenOption.DSYNC}
• B.  try (BufferWriter br = Files.newBufferedWriter (path, Charset.forName ("UTF - 8"), new
  openOption []
  {StandardOpenOption.CREATENEW, StandardOpenOption.APPEND,
  StandardOpenOption.SYNC}}
  }
• C.  try (BufferWriter br = Files.newBufferedWriter (path, Charset.forName ("UTF - 8"), new
  openOption [] {StandardOpenOption.APPEND, StandardOpenOption.ASYNC});) {
• D.  try (BufferWriter br = Files.newBufferedWriter (path, Charset.forName ("UTF - 8"), new
  openOption []
  {StandardOpenOption.CREATE, StandardOpenOption.Append, StandardOpenOption.DSYNC}};}
  {
• E.  try (BufferWriter br = Files.newBufferedWriter (path, Charset.forName ("UTF - 8"), new

Given the code fragment:
Path path1 = Paths.get("D:\\sales\\.\\quarterly\\..\\report");

System.out.println(path1);
System.out.println(path2);
}
What is the result?

• A.  \sales\report
• B.  D: \sales\report
