(B) Russia’s land area per square mile is much smaller.
(C) Russia has more valuable natural resources that are easily available.
(D) The harsh climate is much more suitable for agriculture.

(A) The harsh climate makes much of Russia’s territory unhabitable.

Explanation:

The population density of the United Kingdom is much higher than Russia because of the climatic difference between the countries.

Most of the population in Russia lives in the southern region while the entire eastern and northern regions are uninhabited. Russia has a harsh climate which makes the land of Russia unhabitable and it is the frozen tundra that do not allow more population to live in Russia. Most of the land of Russia is made up of permafrost, the soil that is frozen for many years which contributed to the unhabitable area of Russia.

Hence, the correct answer is "(A) The harsh climate makes much of Russia’s territory unhabitable."
