It is not possible to answer this question without knowing the sampling resolution. Each sample could be converted into either 8,16 or 24bits. The question is incomplete without this information.
You might want to mention that to your teacher  Also, we don't do homework. Regards David

Well if your were using Pulse-code modulation (PCM) encoding it would be,
44,000 sample per chanel per second X 2 stereo channels X 4 sec x 16 bits per sample = 5632000 bits Divided by 8 bits per byte = 704000 bytes 1 KB is normally 1024 bytes so this would mean the answer is E) 687.5 KB If you were not using PCM encoding (for example you were using MP3), then the result would be very different. -------- David PassMark
