Hi,
I would say C, <span>A dog endures hardship but ends up going back to where he is meant to be.
Buck (the dog in 'The Call of The Wild') is taken from his master and mistreated but is finally released into the wild in the end.

The correct answer is C, subject. A cannot be correct as a direct object in this sentence are 'section', and 'discoveries'. B cannot be correct as there is nothing to possess, if it said 'whose', then it would be a possessive relative pronoun, and plus, 'possessive' isn't a function, it is just a kind of pronouns. D is also incorrect, it cannot be an object of preposition because 'anyone' isn't a preposition, it is a pronoun. And since 'who reads the science section of the newspaper' is a part of the whole noun phrase starting with 'anyone', which is a subject, this has also got to be the subject.
The correct answer is A. You are right.
