The choices for this question are needed so as to determine which really is suitable for using the meter units. These are as follows:
a. Measuring a wingspan of a certain insect b. measuring the height of a specific building. c. measuring the length of a single ant. d. measuring the distance between two cities
I think the correct answer would be B. The SI unit of measure for length the meter would be most appropriate when measuring the height of a specific building. Using it for the measurement of the wingspan of an insect and the length of an ant would still be acceptable but these subjects are very small and it would be best to use a smaller scale like millimeters or centimeters. For the measurement of the distance between cities, it would be best to use the units of miles as it has a bigger scale than a meter.
