C Correct answer
Explanation

For 2 years at 8%: Amount = 30000 × (1.08)² = 30000 × 1.1664 = 34992. For remaining 6 months at 4% (half rate): Interest = 34992 × 0.04 = 1399.68. Total compound interest = (34992 - 30000) + 1399.68 = 4992 + 1399.68 = 6391.68. The half-year uses half the annual rate, consistent with compound interest principles.
