Which of the following identifies the cause and corrective action for an image with overlapping of the proximal contacts in which the overlap appears more severe in the posterior region than the anterior region?

A) Mesiodistal projection of the central ray caused the error. Shift the tube toward the anterior to correct this error.
B) Mesiodistal projection of the central ray caused the error. Shift the tube toward the posterior to correct this error.
C) Distomesial projection of the central ray caused the error. Shift the tube toward the anterior to correct this error.
D) Distomesial projection of the central ray caused the error. Shift the tube toward the posterior to correct this error.

B
Explanation: A) If there is less overlap in the anterior region, a mesiodistal projection of the central ray is the cause. To correct this error, the tube should be shifted toward the region where the overlapping is more severe. In this case, the tube should be shifted toward the posterior.
B) If there is less overlap in the anterior region, a mesiodistal projection of the central ray is the cause. To correct this error, the tube should be shifted toward the region where the overlapping is more severe. In this case, the tube should be shifted toward the posterior.
C) If there is less overlap in the anterior region, a mesiodistal projection of the central ray is the cause. To correct this error, the tube should be shifted toward the region where the overlapping is more severe. In this case, the tube should be shifted toward the posterior.
D) If there is less overlap in the anterior region, a mesiodistal projection of the central ray is the cause. To correct this error, the tube should be shifted toward the region where the overlapping is more severe. In this case, the tube should be shifted toward the posterior.
