People from the United States pledged $3.3 billion to support the rebuilding efforts in Haiti following the 2010 earthquake there. However, after 3 years, half of the money has not been dispersed, and nearly 500,000 people still live in tents. As a result, many who have made pledges have decided not to fulfill the remainder of their pledges because of the inaction on the part of the relief fund in getting the funds dispersed, the buildings rebuilt, and the housing constructed.

What would be their grounds for terminating the payment of their pledges?

a. Misrepresentation

b. Fraud

c. Undue influence

d. Lack of performance
