Explanation:

The problem is about identifying the region in the Russian realm with a humid temperate climate. By referring to the climate map and the legend (where C represents humid temperate climate), we can check each option. The areas near the Black Sea are marked with Cfa (a type of humid temperate climate). Russian lands bordering the Caspian Sea have dry climates (BSk etc.). Extreme northeastern Russia has cold polar (E) or humid cold (D) climates. The area around Moscow has a humid cold (Dfb) climate.

Answer:

the areas near the Black Sea
