The answer would be  19. hope that helped

It's C, 19. How I got it is by look at the first number next to the decimal, if the number is 5 or higher then the number goes up just by one. For an example: 10.45 rounded would just be 10 because the number next to the decimal is lower than 5 but 10.55 rounded would be 11 because the number next to the decimal is 5. I hope this helped!!!
