Answer 1

The correct option is C It is the permanent frozen upper soil seen in the Tundra regions.

Due to the cold, the upper soil surface of the region is frozen into a rock-like state all through the year. This is called ‘permafrost’.As there is little soil, only some small plants can grow. The underground soil being hard, it is difficult for trees to grow.
