Which error-checking code uses extra parity bits inserted at specific positions to detect and correct single-bit memory errors?

ACyclic Redundancy Check (CRC)
BChecksum
CHamming Code
DLRC (Longitudinal Redundancy Check)

Explanation

Hamming Code is an error-correcting code (ECC) that detects up to two-bit errors or corrects single-bit errors by placing parity bits at power-of-two bit positions (1, 2, 4, 8, etc.). CRC is widely used for error detection in networks.
