Nasolacrimal duct drains into:: (A) Superior meatus, (B) Ethmoidal bulla, (C) Inferior meatus, (D) Middle meatus
Answer is C. Key Concept:

 The inferior meatus lies underneath the inferior concha, and is the largest of the three meatuses. 
 The nasolacrimal duct opens into it at the junction of its anterior one-third and posterior two-thirds. 
 This opening is guarded by the lacrimal fold, or Hasner’s valve.
