1, I agree. 'relations' has nothing wrong:
relations [plural]
a) official connections between countries, companies, organizations etc
Relations between the two countries have improved recently.
2. I am highly skeptical of the usage of 'relation of A withB'. does anybody have an example?
relation between
the relation between prices and wages
The price the meat is sold for bears no relation to (=is not connected to) the price the farmer receives.
3, why is C wrong?
