Answer:
B
Step-by-step explanation:
Suburns are considered true burns (it's in the name I mean...)
Sunburns do not just cause a reddening of the skin, if you've ever had it you know how much worse it is than just the red color and how it hurts too. Plus, sunburns can drastically increase your risk of skin cancer and stuff you know?
Sunburns can be 1st or 2nd degree, but most of the time it is a 1st degree burn. Either way, don't get a sunburn, it hurts so bad just wear sunscreen.
