A)in the same direction as its image
B)above the direction of its image
C)below the direction of its image
D)More information is needed.

When an object is viewed through the top surface of a block at a non-zero angle, its image appears to be shifted downward from the actual position of the object. This is because the light rays from the object refract when they enter and exit the block, causing them to bend away from the normal. Since the plastic block has an index of refraction of 1.40, the amount of bending is greater than it would be in air, which means the image appears even lower. Therefore, the object is located above the direction of its image.
