A charity called on companies to donate tents to an area hit by torrential rain. As a token of gratitude, a certain area asked the organization which companies had donated. After investigation, we found that: (1) none of the four enterprises donated; (2) the D enterprise did not donate; (3) at least one enterprise of the B enterprise and the D enterprise did not donate; and (4) there were indeed corporate donations among the four enterprises. It was later learned that two of the above four situations were true and two were false.
Based on this, it can be concluded that Enterprise D made a donation.
