"which" is used for non-essential clauses, and is offset by commas "that" is used for essential clauses, and is not offset by commas E.g. The car, which was blue, caused the accident The car that was speeding caused the accident

The clause "which is the biggest country in the world" is extra information about Russia. You can remove it without changing the meaning of the main sentence ("Russia is very cold.") It must be marked with commas. Punctuation is important! :)

你用中文感受一下: 1、俄罗斯这个世界上最大的国家非常寒冷。 2、俄罗斯——世界上最大的国家,非常寒冷。

A is incorrect because after you say Russia, there should be a pause, which is indicated by a comma ( , ). In this context, it is like when you use a full stop ( . ) to break up sentences and make them easier to understand. I hope that helps

It is B, for the reason Peachey says. However, I would say it's still not good stylistically, because the size has nothing to do with the coldness. A better example would be something like "Russia, which is the biggest country in the world, has a lower population than some other countries".
