The largest unit of measure among the options given is C 1 ton.
To clarify the measurements:
- 1 ton = 2000 pounds (in the US customary system)
- 1 pound (lb) = 16 ounces
- 1 gram (g) is a much smaller unit, where 1 pound is approximately 453.592 grams.
Thus, 1 ton is significantly larger than 1 lb or 1 g.
