*will mark brainlist*
a.
they are exactly as we see them.
b.
they are upside down and reversed left to right.
c.
they are only upside down.
d.
they are only reversed left to right.

Answer B: They are upside down and reversed left to right.

Explanation:

The ray trajectory through a thin lens is can be perfectly mapped with geometry which is normally a representation of an object (in most cases an arrow is used) and rays parallel to the optic axis then bending towards the focal point  and intercepting with rays that go straight through the lens' geometrical center.

Notice that if we are dealing with a circular lens like the one in the eyes, this ray trajectory will always give an inverted image independent of whether you are considering an upright object or an object that is horizontal. You just need to rotate the image-lens system 90 degrees so you can again draw the ray trajectories as before resulting on reversed images.

That is: the lens will always invert the image (from upright to pointing downwards, or from pointing right to pointing left). The lens will always  reverse the image.

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.
