A
3%
💡 Explanation:
This is a factual recall question about prevalence statistics. Phonological disorders (speech sound difficulties) of unknown origin affect approximately 3% of preschool children. The exact percentage varies by study and diagnostic criteria, but 3% is the most commonly cited figure in speech-language pathology literature. Without access to current statistics, D (3%) is the best choice among the options.
