The picture shows a photo taken by a high-speed camera at the moment when a bullet penetrates an apple. After the photo is enlarged, it can be distinguished that the bullet image is staggered before and after the exposure time.
The average size of an apple is about 1cm, so it can be seen that the bullet is about 5cm. Therefore, the displacement of the bullet during exposure is about 5× 1-4 m ~ 1× 1-3 m. According to the displacement formula, the exposure time is about 1 -6 s．, so B is correct.
Therefore, B is selected.
