Which trend do the data in the maps support ? ?

In the given maps, there shows the temperature anomalies in both land as well as sea surface. In the sea surface, the temperature anomaly ranges from -5°C to 5°C which is comparatively lesser than the land temperature i.e -12°C to 12°C.

Thus from the provided data in the map, we can conclude that the average temperature in the land surface is more than the sea surface because the sea surface has the capacity to reflect back heat to the atmosphere but land surface cannot reflect much of it, thereby becomes more warmer as it absorbs most of the incoming solar radiations.
