The correct option is D Thousandths
Let's understand this concept using an example:
Example: When we estimate 12.872 to the nearest hundredths we look at 2 (in thousandths place) to do the estimtion.
Here 2 (in thousandths place) is less than 5, so we keep a digit in hundredths place as it is.
So, 12.872 is estimated to 12.87
Thus, "we should look at thousandths place when we are estimating the values to nearest hundredths".
