A meter is the basic unit for measuring what? A. Volume
B. Weight and mass
C. Length and distance
D. Time

C

Explanation:

A meter measures distance. We don't say the cube is x meters long, just as we don't say we weigh x amount. Instead we use units like centimeters for volume while we use pounds or kilograms for weight. In terms of time, I have no idea how the unit meters would be useful for that. Example for time units include: seconds, minutes, hours, and days. However, we do say this ruler is x amount of meters. As such, length and distance is the only logical answer.
