The Sodor Railway Trust (A Registered Charity) Has Been Raising

The Sodor Railway Trust (a registered charity) has been raising money for the rebuilding of the Sodor coastal line, a steam and heritage railway project estimated to cost about £10 million. When the Trust had raised about half of this sum, a massive landslide made the project completely unviable.
Which of the following statements about the money raised by the Trust is least accurate?

A) The Trust is not entitled to receive a legacy from Rocky, who had promised to make a gift in his will, and who died a month after the landslide.
B) The Trust is obliged to return to the original contributors any money raised through cash deposited in collecting boxes to the extent to which such contributors can be identified.
C) The trust is not obliged to return any funds to any contributor who was told before the donation that in the event of the project failing, the funds would be applied to alternative charitable purposes.
D) The trust must return larger donations to any donor who can be identified, using advertisements and inquiries if necessary.
