Giving Brainliest if u help me with this

B. The western coast of the united states

Explanation:

I'm not sure if its correct but its pretty simple to understand, if you look at the arrows red represents heat, and blue represents cold,  the red arrows (warm climate) is at the left more towards the U.S, therefore looking at the guide of North West South and East, it is at the western coast of the u.s

Hope this help! <3
