Answer:
B) Pounds
Explanation:
If we want to weigh something, we should use measurements such as pounds or grams. This automatically rules out options 'a' and 'd'.
This leaves us with C and B. Pounds are normally used to weigh humans, while tons may be used to weigh a building, car, or VERY large animals.
1 ton = 2000 lbs.!
A small puppy would probably only be max 25lbs. So pounds is the answer.
