What does the difference in size between icarus and the farmer at the forefront most clearly suggest?

a-the farmer plays a bigger role in the landscape than icarus.
b-icarus's drowning is more dramatic than the farmer's work.
c-icarus and the farmer are of equal importance.
d-icarus and the farmer are at an equal distance from the ship.

The answer is A. (I'm assuming you're talking about Landscape With the Fall of Icarus by Peter Bruegel.) 
Icarus is hardly visible in the artwork. The farmer is very clearly visible in the front. This shows that the artist is trying to emphasize the farmer and also show that Icarus is very insignificant compared to the rest of the scene, so all the other answer choices are incorrect.
Hope that helped you.

Eh. what sentence hotness?
