The correct answer is C. Both 1 and 2.
The rate of warming in Shimla is more than Srinagar. This is because Shimla is located in a lower altitude than Srinagar, and is therefore more exposed to the effects of climate change. The snow line in Himachal Pradesh has shifted upwards, and the growth of pine and coniferous trees has reduced. This is because climate change is causing the temperature to rise, which is making it more difficult for these trees to grow.
Option A is incorrect because statement 2 is also correct. Option B is incorrect because statement 1 is also correct. Option D is incorrect because both statements are correct.
