Answer:
The right answer to this question is: 310k
Explanation:
There's a very good formula that can help us to find this answer, but first, we need to know the temperature scale  in Celsius and Kelvin, there's an image below that will help us gather information. 
The formula is quite simple, check it below:
C/5  = K-273/5
putting the values we already have in the formula it would be like this:
37/5 = K-273/5
Cutting out the fives, we can have the final result
37= K-273
37+273 = K
K= 310.

Without seeing the image ...I can suggest C as bacteria and archae are the most similar besides all other options ! am I right !!!
