Final answer:
To arrange the measurements from smallest to largest is B. 0.123 K, 125 g, 1,203 mg.
Step-by-step explanation:
To arrange these measurements from smallest to largest, we need to convert them to a consistent unit of measurement. Let's convert them all to grams:
0.123 K = 0.123 × 1000 g = 123 g
1,203 mg = 1.203 g
125 g
The order follows the principle of arranging in ascending order, from the smallest to the largest. We converted the measurements to a common unit, grams, and then compared them to determine the order. Therefore, the correct arrangement is B) 0.123 K, 125 g, 1,203 mg.
