Noise in childcare spaces should not exceed 35-40 decibels. A) at least 50 percent of the time. B)at least 25 percent of the time. C) at least 80 percent of the time. D) at any time.

D) at any time.

Explanation:

Noise is defined as an objectionable or unwanted or sound. Noise in childcare spaces more than 35-40 decibels can be really harmful to children as it affects the hearing and neurological sense of children.

Noise more than 35-40 decibels should not exceed at any time as children are very sensitive to noise and loud noise can cause a temporary decrease in hearing and repeated exposure to noise can cause permanent or temporary hearing loss, so noise should not exceed 35-40 decibels at any time in childcare spaces.

Hence, the correct option is "D".
