The determining date to qualify for deductions is October 1. Which term completes the blank?

• A. Ownership
• B. Residency
• C. Age
• D. Marriage

Answer: (A)

Ownership is the determining factor because the rule uses who holds legal title to the asset on the cut‑off date to decide eligibility for the deduction. If you own the asset as of October 1, you meet the criterion for the deduction for that year; if you don’t own it by that date, you don’t qualify. This date-based ownership standard is what makes the deduction possible and predictable, avoiding mid-year changes from altering eligibility. Residency, age, and marriage describe where you live or who you are, but they don’t establish this specific ownership‑by‑a‑date requirement, so they don’t fit the rule as described.
