To determine who has the highest protein DRI per unit of body weight, we need to compare protein requirements on a per-kilogram basis across age groups.

Option 1: a 28-year-old woman. In healthy adults, the DRI for protein is about 0.8 g per kg of body weight per day. This value is a standard baseline for adults and is lower on a per-kilogram basis than that for growing children.

Option 2: a 28-year-old male. While men may require slightly more total protein than women due to body size, the per-kilogram requirement in adults remains around 0.8 g/kg/day. It is not higher than that of children.

Option 3: a 34-year-old woman. Similar to other adults, this individual’s per-kilogram protein requirement is near 0.8 g/kg/day, which is generally lower than that of children when expressed per kg.

Option 4: a 40-year-old male. Again, adult per-kilogram needs are about 0.8 g/kg/day; this does not exceed the per-kilogram needs seen in growing children.

Option 5: a 6-year-old child. Children in the growth phase have higher protein needs per kilogram to support tissue synthesis and growth. Their per-kilogram DRI for protein is notably greater than that of adults, making this group the highest on a per-weight basis.

In summary, although adults require a fixed amount of protein per kilogram that supports maintenance, the rapidly growing child has the highest per-kilogram protein requirement due to ongoing development and tissue synthesis. Therefore, the 6-year-old child would have the highest protein DRI per unit of body weight.
