The answer is D. 19.87,because if you multiply them you really get 19.872,
but the 8 is in the tenths place, and the 7 is in the hundredths place, and the 2 is in the thousandths place. And we wanted to round to the nearest hundredths place, which give us 19.87, but if the 2 was a five or higher it would have been, 19.88.
BUT THE ANSWER IS 19.87
