Explanation:

In electron microscopy, regions of a specimen with higher density contain more atoms to interact with electron beams. This increased interaction scatters more electrons away from the detector, resulting in a darker appearance in the final image. Less dense regions scatter fewer electrons, allowing more to reach the detector and appear lighter.

Answer:

B. The most dense region
