Solution

The correct option is C Assertion is correct but Reason is incorrect
Whenever we change the unit of measurement of a quantity, its measured value changes by an amount of conversion factor. Therefore, assertion is correct.
The smaller the unit of measurement, Higher the conversion factor. Therefore, higher the numerical value. So, reason is false.
Hence, Option C is correct
