Answer
Assertion (A) is true but Reason (R) is false.
Explanation
In 15.406, the hundredths place is 0. The digit in the thousandths place is 6 > 5, so we increase the hundredths digit by 1 to get 15.41.
The Reason is false.
Nearest hundredths means correct to 2 decimal places, not 3 decimal places.
Hence, option 3 is the correct option.
