Final answer:
Near Field Communication (NFC) operates with low bandwidth and is designed for a very short communication range, typically within a few centimeters. Therefore, the correct answer is option 1: low BW and low range.
Step-by-step explanation:
The technology we are discussing is Near Field Communication (NFC), which is used for a variety of applications, but most commonly for secure and quick data exchange over a very short distance. NFC operates at a specified radio frequency of 13.56 MHz, which places it at the low-frequency and long-wavelength end of the electromagnetic spectrum (referencing Section Summary options c and d).
Given the characteristics of NFC, and within the context of the provided information, we can determine that NFC has a low bandwidth (BW) and is intended for a low range of communication. This is typically no more than a few centimeters. Consequently, the correct answer to the student's question is option 1: low BW and low range.
NFC's low bandwidth is sufficient for the kinds of quick, small data transfers it was intended for, such as contactless payment systems or exchanging contact information between devices.
