Answer:
c. The transaction history indicates a pattern of wire transfers to countries with no previous connection to the charity's activities.
Step-by-step explanation:
Any type of Non profit organization or charitable institute is the most risky institution for terrorist financing, hence the transactions which are being performed by the charitable organization to countries which were not previously included in the transfers list will raise a red flag for potential terrorist financing and strict due diligence will need to be performed of that organization because there may be the case that those wire transfers are helping the terrorist finance their cost through legal means i.e from a charitable and well known organization. And this is how all this terrorist financing works.
Hope this clear things up.
Good luck.
