Question:
Which of the following is true about master apical file? 

Options:
{'A': 'The last file which is selected for the obturation', 'B': 'The initial file which is selected for initial radiographic working length', 'C': 'The smaller file used in between the other file during biomechanical preparation', 'D': 'The last file which is used for removal of soft debris from root canal'}'

[2025-09-30T03:09:23.710786] [PI reasoning] **Clarifying dental terminology**

I’m answering a dental question about the Master Apical File (MAF). The MAF is the largest file that reaches the full working length during canal preparation, determining the final apical size before obturation. The options provided include some ambiguities. 

Option A might cause confusion since it mentions "selected for obturation," but it's actually the last file used for instrumentation. Option B refers to the initial file, which isn’t correct. Options C and D also refer to different types of files.
