The correct option is C The Governor told him that he had to make his oath in front of the sheriff at Inverary about 60 miles away
King William III had ordered all Scottish clans to swear an oath of loyalty to him by New Year's Day the following year. When Maclain MacDonald, chief of the MacDonalad clan reached Fort William to make his oath, the Governor told him that he had to make his oath in front of the sheriff at Inverary which was about 60 miles away.
Thus, option C is correct.
