Final answer:
Helen will receive a step-up in basis to the fair market value of the investment land.
Step-by-step explanation:
B. Helen will receive a step-up in basis to the fair market value of the investment land.
When Tripp transfers the investment land to Helen, she will receive a step-up in basis to the fair market value of the property at the time of transfer. This means that Helen's new adjusted basis for tax purposes will be the fair market value of the property when she received it.
Therefore, statement B is true.
