Final answer:
The correct DMFS (Decayed, Missing, Filled Surfaces) score for the adolescent is given as 14. Thus, the answer to the student's question is option (b) 14.
Step-by-step explanation:
The student is asking about the DMFS (Decayed, Missing, Filled Surfaces) score in the context of dental health.
This is a commonly used index that dentists and researchers employ to measure the amount of dental caries in an individual's teeth.
The DMFT (Decayed, Missing, Filled Teeth) score refers to the number of teeth affected by caries, while the DMFS score reflects the number of individual tooth surfaces affected.
In this scenario, the DMFS score is already provided as 14. Therefore, the correct option is (b) 14, as mentioned in the final answer.
