D
Correct answer
Explanation
Dental health recommendations consistently advise brushing twice daily - typically morning and night - to maintain optimal oral hygiene. Brushing thrice daily isn't necessarily harmful but isn't the standard recommendation. Brushing after every meal can actually damage enamel if done too soon after acidic foods. While nighttime brushing is crucial, the complete recommendation is twice daily.
