Hmm, line n1 looks a bit tricky. I'd go with C. br.flush() to make sure the input stream is up-to-date before writing to the output file.

I think C is the right choice too. It ensures all data is written to the output file.

I agree with Elfrieda, D) bw.flush() is the right choice to ensure the data is written to alldata.txt.

But if we want to overwrite alldata.txt with data.txt, we need to flush the BufferedWriter, so D) bw.flush() makes more sense.

I disagree, I believe the correct answer is A) br.close(). It will close the BufferedReader after reading data.txt.

I think the answer is D. bw.flush() is required to ensure that all buffered output bytes are written out to the underlying output stream.
