B Correct answer
Explanation

Pattern: Each term = first three digits reversed × 10 + last digit. 4885: 488 × 10 + 5 = 4885. 3516: 351 × 10 + 6 = 3516. 4607 should be 467 × 10 + 7 = 4677, not 4607. 3764: 376 × 10 + 4 = 3764. 4389: 438 × 10 + 9 = 4389. 3948: 394 × 10 + 8 = 3948. Only 4607 breaks the pattern.
