Final answer:
The described melting snowmen heads are best represented by Option 4, a spring day with melting snow, echoing the surprising and transformative art of Arcimboldo and symbolizing the seasonal shift from winter to spring in both art and literature.
Step-by-step explanation:
The scenario described in the question, where snowmen heads with missing coal eyes and carrot noses are melting, most closely resembles Option 4: A spring day with melting snow. Arcimboldo's composite heads, as mentioned, play with the viewer's perception, transforming elements of nature into facial features, creating a surprising and sometimes bewildering effect similar to the melting snowmen scenario. This melting could symbolize the transition from winter to spring, with warmth causing snow to recede, captured in artworks like the Haystacks (Effect of Snow and Sun), and evoked in literary depictions of winter landscapes transitioning into springtime.
