Right option is (a) Large transmission bandwidth

Easy explanation: Spread spectrum systems are bandwidth inefficient for single users. But in spread spectrum systems, many users can simultaneously use the same bandwidth without significantly interfering with one another. It is one of the advantages of spread spectrum.
