The Options (a) and (c) apply to the question, i.e. the digit 2 increases in value from 2 ones to 2 hundred, and, the digit 3 shifts 2 places to the left, from the tens place to the thousands place.
32.4×10²=32.4×100=3240
Hence, digit 2 moves from one's place to a hundred's. (a) satisfied
And similarly, digit 3 moves from ten's place to thousand's place. Now, 1000=10³=10²×10.
Hence, it shifts 2 places to the left.
Therefore, (c) is satisfied.
As for (b), where the statement: Each place is multiplied by 1,000; the statement does not hold true since each digit is shifted 2 places, which indicates multiplied by 10²=100, not 1000.
Hence (a) and (c) applies to our question.
