Let’s check the given options:
1) 8B6D2A4C3 ⇒ 8 - 6 ÷ 2 + 4 × 3
⇒ 8 - 3 + 12 = 17
Hence, it is false.
2) 8A8B8C8 ⇒ 8 + 8 - 8 × 8
⇒ 8 + 8 - 64 = 16 - 64 = -48
Hence, it is true.
3) 9C9B9D9A9 ⇒ 9 × 9 - 9 ÷ 9 + 9
⇒ 9 × 9 - 1 + 9 = 81 + 8 = 89
Hence it is false.
4) 3A3B3C3A3D3 ⇒ 3 + 3 - 3 × 3 + 3 ÷ 3
⇒ 3 + 3 - 3 × 3 + 1 = 3 + 3 - 9 + 1 = -2
Hence it is false.
Hence the correct equation is 8A8B8C8 = -48.
