Question

why is the si unit for mass kilograms and not grams?
it is because a gram is too large to use on a regular basis
it isnt. the si unit for mass is grams, not kilograms
it is because a kilogram is a more measurable quantity
it is because kilograms are smaller and easier to use

Explanation:

• First option: Gram is small, not large, so wrong.
• Second option: SI base unit for mass is kilogram, so wrong.
• Third option: Kilogram is more practical for common measurements (e.g., daily objects), so this makes sense.
• Fourth option: Kilogram is larger than gram, so wrong.

Answer:

C. It is because a kilogram is a more measurable quantity (Note: The original options don't have letter labels, but the third option is the correct one. If we assume labels as A, B, C, D for the four options in order, the correct one is the third, so C. It is because a kilogram is a more measurable quantity)
