The metric unit for weight is kilo.
The best prefix for measuring large quantities such as a person's mass is kilo , which represents 1,000 grams, or 1 kilogram. Other prefixes like milli, deci, and deca are not practical for such large measures. Therefore, the answer to the question is option B: kilo.
