Answer:
C. 5,000 grams.
Explanation:
This answer variates according to dog breeds. However, this is a logical question, because just one option make sense, which is C. Because dogs cannot weight 15 grams or 50 grams as average, those are weights for another animal, but a dog, logically, weighs more than that.
So, option C is a reasonable answer among the options.
In addition, according to Purina, average dog weight is a myth, because as we said, this depends on other variables, like to different breeds.
