Final answer:
(b) The correct valuation technique for reducing the value of Alice Brittain's estate for the tree nursery business is a special use valuation, as it applies to property used for farming or family businesses passed to a family member.
Step-by-step explanation:
The valuation technique that would be appropriate to reduce the value of Alice Brittain's gross estate is b) A special use valuation on the family nursery. This is because special use valuation can apply to real property used for farming or a closely-held business, like the tree nursery business in question. Special use valuation allows the property to be valued based on its actual use rather than its highest and best use, potentially leading to a lower estate valuation and thereby reducing estate taxes.
This valuation technique is applicable when the property is passed on to a family member who intends to continue the business. The blockage discount would not apply as the size of the stock holdings in relation to the total number of shares and trading volume is not large enough to justify it. The alternate valuation date for the annuity is also not applicable here as it concerns the timing of estate valuation, not a reduction in value. Lastly, the minority discount does not apply because there is no minority interest; Alice solely owns the business.
