D
Option A: 9 dollars comma 597 point 2 2, Option B: 9 dollars comma 587 point 6 7

Explanation

Use the compound interest formula with P = 8,000, r = 0.0315, and t = 6. For Option A, quarterly compounding means n = 4, so 8,000(1 + 0.0315/4)^(4×6) rounds to $9,657.18. For Option B, daily compounding means n = 365, so 8,000(1 + 0.0315/365)^(365×6) rounds to $9,664.25. These amounts match choice C; daily compounding gives a slightly higher total.
