One wants to anaesthetise the inferior alveolar nerve at the point at which it exits from the mandibular canal, so the injection site most often located in
1. Between first and second molars inferior to the root apices
2. Between first and second molar superior to root apices
3. Between first and second premolars inferior to root apices
