The correct answer is C) gram. The metric unit used to measure the mass of an object, including a grasshopper, is the gram. To arrive at this answer, you can recall the basic metric unit system and its prefixes. The base unit for measuring mass in the metric system is the gram (g). The centimeter (cm) and meter (m) are units of length, not mass. Therefore, you answered correctly by choosing gram (C) as the appropriate unit for measuring the mass of a grasshopper.
