Answer: D -DSSS communicates by adding data that is to be transmitted to a higher speed transmission.

Key Takeaway: With DSSS, the transmitted signal takes up more bandwidth than the information signal that is being modulated. The benefits of DSSS include resistance to intended or unintended jamming, sharing of a single channel among multiple users, reduced signal/background-noise level, lower interception, and better timing between transmitter and receiver. FHSS accomplishes communication by hopping the transmission over a range of predefined frequencies. OFDM communicates by breaking the data into sub signals and transmitting them.
