What is the primary etiological factor for the development of root caries?

Poor dental hygiene
High sugar diet
Acquired xerostomia
Genetic predisposition

The correct answer is: Acquired xerostomia

Acquired xerostomia, also known as dry mouth, is the primary etiological factor for the development of root caries. Poor dental hygiene and a high sugar diet can contribute to the development of cavities and other dental problems, but they are not the primary cause for root caries. Additionally, while genetics can play a role in an individual's susceptibility to cavities, there is no specific gene or genetic predisposition for root caries. Therefore, options A, B, and D are incorrect as they are not the primary etiological factor for root caries.
