Answer 1

The Correct Option is C

Step 1: Understanding the Concept
A "meaningful order" in measurements usually refers to arranging units from the smallest to the largest (ascending) or largest to smallest (descending).

Step 2: Key Formula or Approach
The metric prefixes in increasing order are: Milli < Centi < Deci < Unit (Gram) < Deca < Hecto < Kilo < Tonne.

Step 3: Detailed Explanation
Let's convert all to grams for comparison: 1. Milligram (2): 0.001 g (Smallest) 2. Decigram (5): 0.1 g 3. Decagram (3): 10 g 4. Hectogram (1): 100 g 5. Tonne (4): 1,000,000 g (Largest) Arranging from smallest to largest: 2, 5, 3, 1, 4.

Step 4: Final Answer
The correct order is 2, 5, 3, 1, 4.
