The most accurate response is:
**Sea ice has melted, allowing more sunlight to hit the ocean.**
Melting sea ice reduces the reflective surface that typically bounces sunlight back into the atmosphere, leading to increased absorption of heat by the ocean, which contributes to temperature increases in the Arctic Ocean over the last 40 years.
