A) behind the distal half of the first premolar.
B) behind the distal half of the second premolar.
C) in front of the mesial half of the first premolar.
D) in front of the mesial half of the second premolar.

B
Explanation: A) When placing the image receptor to image a molar horizontal or vertical bitewing radiograph, the radiographer should focus on placing the anterior edge of the image receptor so that it lines up behind the distal half of the second premolar.
