I think the correct answer from the choices listed above is option D. The figure of speech being used here is a simile. The use of the word "as" shows that a simile is being used to compare the quality of the fleece to snow. Hope this answers the question. Have a nice day.
Here are two examples : '' So Carnehan loaded the mules with the rifles that was taken off the camels, and together we starts forward into those bitter cold mountainous parts, and never a road broader than the back of your hand.''
'' My eye could detect no failure in the disguises. The scene in the Serai attested that they were complete to the native mind. There was just the chance, therefore, that Carnehan and Dravot would be able to wander through Afghanistan without detection.''
The action of Carnehan preparing things for his journey show that they are taking this adventure seriously and truly wish to accomplish their goal of becoming kings. Although they had trials and tribulations to face, they are stepping up to the plate and conquering them.
If it is by Andy Singer, I would say energy conservation.
