Final answer:
Option (c), A gift of income to charity with remainder to children is an example of a charitable lead trust, where the charity receives income for a certain period and the remainder goes to the donor's children.
Step-by-step explanation:
A gift of income to charity with remainder to children is an example of a charitable lead trust. This type of trust allows the donor to give assets to a charity for a period of time, after which the remaining assets pass to the beneficiaries, such as the donor's children. In a charitable lead trust, the charity receives the income interest first, and the non-charitable beneficiaries receive the remainder interest.
