Detailed Solution

Concept: First, convert all specified options to the same decimal place or the same number of decimal places.
Then you can sort all the options in ascending order.
First, all options must have the same number of decimal places or the same number of decimal places. This process is performed by adding zeros to the end of the number until the desired number of decimal places is reached. For example, if you want to create 52. 02 with 5 decimal places, just add a zero at the end, like 52. 02000. This will have 5 decimal places for the specified number.
Now, we will follow the same process for the options as well.
0. 500, 0. 420, 0. 382
11. 001, 11. 100, 11. 210
20. 30, 30. 02, 23. 45
8. 900, 8. 860, 8. 094
Then check and get the ascending order of each specified option
11. 001, 11. 100, 11. 210 is the only option which is having an ascending order
Hence, the correct answer is option (2).
