In the first one - The correct answer choice A - uses semicolon.
In the second q - The correct answer choice C - does not.
The reason being "latter of which" is dependent(from the answer explanation).
However, in the first one as well, the usage of "this proportion" should be dependent on the first clause. Because until we get information from the first clause of what "this" is, the second clause does not make sense.
From these examples - I can say that the pronouns in one clause where antecedent in residing in the second clause are accepted. Then, why "latter of which" is not. Are there any specific instances like "latter of which" where semicolon cannot be used.
