Quipus, used by the Inca civilization in South America, conveyed information through a pattern of knots on strings (option B). Unlike written records kept by many European and Asian societies, which often relied on alphabets or scripts, quipus served as a unique system for recording data, such as statistical information, administrative details, and possibly narratives, using different colors and arrangements of knots.
Therefore, the key difference lies in the method of information encoding: quipus did not use a pictorial or phonetic alphabet, and they were not oral records but rather a distinct tactile method of representation.
