Answer:
A) Gift loans of $14,000 in which interest foregone is in the form of a gift.
Explanation:
You are free to give anyone any type of gift that is worth up to $14,000, this includes gifts in cash, assets (e.g. car) or gift loans. Any gift above that threshold will result in taxes paid by the person that receives the gift.
The IRS defines gift loans under Section 7872(f)(3) as:
“The term “gift loan” is any below-market loan where the forgoing of interest is in the nature of a gift.”
As long as the forgone interest doesn't exceed $14,000, then no taxes should be paid.
