Answer:
The correct answer is option A.
Explanation:
The metric units are in the following order:
1 Kilogram (kg) = 1000 g
Hectogram (hg) = 100 g
Decagram (dag) = 10 g
gram (g) = 1 g
decigram (dg) = 0.1 g
centigram (cg) =0.01 g
milligram (mg) = 0.001 g
A) 25 g = 25 g
B) 2.5 hg = 2.5 × 100 = 250 g
C) 2,500 dg = 2,500 × 0.1 g=250 g
D) 0.25 kg = 0.25 × 1000 g = 250 g
250 g = 250 g = 250 > 25 g
The smallest amount of matter is 25 g.
