I believe D. because all the organisms that live in a lake can be a bunch of living things that would be considered a population and not a species. I canceled out B. from the get go because, I don’t believe non living organisms can be in a population ?
Please get back to me if I’m right or wrong :)
I think that different liquids have different freezing points because every liquid consists of different atoms and different things that make up the atom causing them to have different freezing points.

Answer:
is reduced in the reaction
Explanation:
The given reaction is
![$2Fe^{2+}+Cl_{2} \to 2Fe^{3+}+2Cl^{-}$](https://tex.z-dn.net/?f=%242Fe%5E%7B2%2B%7D%2BCl_%7B2%7D%20%5Cto%202Fe%5E%7B3%2B%7D%2B2Cl%5E%7B-%7D%24)
The oxidation number of
is changed from ![$+2\, \to \, +3$](https://tex.z-dn.net/?f=%24%2B2%5C%2C%20%5Cto%20%5C%2C%20%2B3%24)
![$Fe^{2+} \to Fe^{3+}+e^{-}$](https://tex.z-dn.net/?f=%24Fe%5E%7B2%2B%7D%20%5Cto%20Fe%5E%7B3%2B%7D%2Be%5E%7B-%7D%24)
And The oxidation number of
is changed from ![$0\, \to \, -1$](https://tex.z-dn.net/?f=%240%5C%2C%20%5Cto%20%5C%2C%20-1%24)
![$Cl_{2}^{0} + 2e^{-} \to 2Cl^{-}$](https://tex.z-dn.net/?f=%24Cl_%7B2%7D%5E%7B0%7D%20%2B%202e%5E%7B-%7D%20%5Cto%202Cl%5E%7B-%7D%24)
Hence,
is oxidized and
is reduced
