Answer

c. 1500 kg

Work Step by Step

A weight of 1500 dag is equal to 15 kg which is clearly too small. A weight of 1500 hg is equal to 150 kg which is clearly too small. A typical African elephant might weight about 5000 kg. If a car weighed 15,000 kg, this would be the weight of three African elephants which seems too large for one regular-size car. If a car weighed 1500 kg, then the weight of one African elephant would be similar to the weight of three regular-size cars. This seems like a reasonable weight for a regular-size car. The best estimate for the weight of a regular-size car is 1500 kg.
