The answer is A
Step-by-step explanation:
That is because one million has 6 digits and I'm guessing that the flea is measured in millimeters. So you just add the two decimal places. So, you add the one million (count the number of zeroes in a million) to the number of decimal places that the dot was moved. So from a measure of meter you move the dot one place right and you decrease the measuring unit. So, first is meter then centimeter and then millimeter.
