B
Explanation: A) Positioning the image receptor close to the teeth satisfies the shadow-casting principle for increasing image sharpness that states a short object-image receptor distance reduces penumbra and magnification.
B) Positioning the image receptor close to the teeth satisfies the shadow-casting principle for increasing image sharpness that states a short object-image receptor distance reduces penumbra and magnification.
C) Positioning the image receptor close to the teeth satisfies the shadow-casting principle for increasing image sharpness that states a short object-image receptor distance reduces penumbra and magnification.
D) Positioning the image receptor close to the teeth satisfies the shadow-casting principle for increasing image sharpness that states a short object-image receptor distance reduces penumbra and magnification.
