The given samples are supposed to weigh 25.0 grams. This value is the basis when we talk about accuracy. In this case, we are talking about precision, so we opt to select the most 'precise' of the choices. The most precise measurement is C) 25.0122 grams. This is because it records up to + - 0.0001 grams.
