The oxidation-reduction reaction from the reactions above is 
ZnS(s) + 2O2(g) ------ ZnSO4(s)
<h3>What is redox reactions?</h3>
Oxidation-reduction or redox reaction is the type of chemical reaction in which oxidation states of substrate changes
So therefore, the oxidation-reduction reaction from the reactions above is 
ZnS(s) + 2O2(g) ------ ZnSO4(s)

Answer:
I believe the answer is B. 
Explanation:
I have never heard of it meaning the coldest point in outer space or freezing point of "pure" water at sea level. As for C, substances have a different points where the molecules stop moving. So the answer that makes the most sense is B.
