Answer:
Wholly owned subsidiary.
Step-by-step explanation:
A wholly owned subsidiary is one that is funded wholly by its owners and does not have external sources to fund their operations. When a wholly owned subsidiary is setting up business overseas it is more expensive because there is no external funds to ease the financial burden of setting up operations abroad.
Since it is wholly owned the owners will also bear more risk in case a failure of the venture occurs. They also bear all the gains earned when operating abroad.
So wholly owned business presents more risk and there is more cost burden involved in setting up services abroad.
