Answer

The best estimate for a newborn infant's weight is: d. 3 kg

Work Step by Step

Lifting a 10-kg sack of potatoes feels much heavier than holding a newborn infant, so clearly 30 kg, 300 kg, and 3000 kg are too large for a newborn infant. A weight of 3 kg is the weight of three one-liter bottles of water. A weight of 3 kg seems reasonable for the weight of a newborn infant. The best estimate for a newborn infant's weight is: d. 3 kg
