Answer 1

Correct option is (d) xG spectrum access

To elaborate: xG network access refers to the communication established via xG base-station on licensed and unlicensed spectrum band. xG ad hoc access refers to communication among xG users using an ad hoc connection on licensed and unlicensed spectrum band. Primary network access refers to the communication carried out using primary base-station on licensed spectrum band.
