Show answer & explanation
Correct answer: C
The primary reason block parity (Longitudinal Redundancy Check) was invented was to catch burst errors (where multiple consecutive bits are corrupted during transmission). If a row experiences a 2-bit error, the row parity check will fail to notice it. However, those two errors will alter two different columns, causing the column parity checks to flag the errors. Therefore, it is highly reliable at detecting multi-bit errors.
