The correct option is D 1002, 2030, 3020, 3302
Ascending order is arranging the numbers from the lowest to the highest.
When we compare the first digit of given numbers, we get to know that 1 < 2 < 3.
And for two numbers that are 3020 and 3302 we need to compare second digit 0 < 3
Hence, ascending order is 1002, 2030, 3020, 3302
