Which is likely to have a mass close to 3 kilograms a) small feather b) five-year-old cat c) grown elephant d) peach

3 kilograms is about 6 pounds, which is reasonable for a cat of that age. It is reasonable to come to the conclusion that 6 pounds is too heavy for a peach or a small feather. Also, that would be far too light to be the weight of a grown elephant, given that they usually weigh a few tons.
