Advances in technology allow several UK firms to begin providing a digital service that did not previously exist. Which conclusion about the effect on the UK economy's real output is best supported?
The service may add to real output and contribute to economic growth
The service may raise nominal GDP without raising real GDP, because it has a selling price
The service may raise GDP only if the firms providing it are UK-owned
The service may add to firms' sales but not to GDP, because GDP counts goods rather than services
